Depends if your local distributor ordered them. Also, Australia is a bit further away

Is it possible to configure two of these up in a P2P fashion ? The license level says 3, so that means it wouldn't be able to be configured as a AP, right? It looks like it has the grunt to do it based on my spec sheet.

mode=bridge is supported for level3, mode=bridge allows to make PTP link.

Like Sergejs said, L3 is enough to make a P2P link.

Will it work if the AP is MT but not N standard (older Atheros card) but has NV2 enabled? In 20Mhz channels. What about same situation with 40MHz channels?
Thank you.

If you set the SXT to mode "any", it will connect using the mode which AP uses. When you replace the AP, it will reconnect with the best mode.

Will it work if the AP is MT but not N standard (older Atheros card) but has NV2 enabled? In 20Mhz channels. What about same situation with 40MHz channels?
Thank you.

Remember that old Atheros chipset cards 40mhz option (turbo) isn't compatible with N cards 2x20Mhz option.
SXT has built-in N Atheros chipset.

Where's the love for 2GHz? Last two products to be released are 5GHz only, I am trying to patiently wait for MUM.

NICE! Finally there is some light at the end of the tunnel. I'd way rather buy MT than the cheap plastic (that seems to work great for CPEs).

Whats the real ETA on these?

and will mikrotik make RB711A-5HnD?
wanna try connect it to ub*t sectoral antenna...

Whats the real ETA on these?

Impressive!!!

Is this product suited for outdoor installations ?

Nice production , esd protection the ethernet port?

It's about time

Any chance to 20 or better 23 dbi version ?

It says it has an extended L2MTU, is this just on the wireless side? or ethernet as well

that's only for ethernet. wireless doesn't have any such limitations

gps sync

no, that's a USB port, an opening for the USB cable, and the opening for ventilation (points downwards when mounted)

Is this product suited for outdoor installations ?

I'll say that it's mostly intended for outdoor, but if you want, you can use it indoors as well. That's a narrow beam directional antenna though.

Hi Normis,

Why USB on a CPE device that already has ethernet? What is your thinking on this?

An alternate port in case the ethernet goes bad? Does it power up from 5 volts on the USB port?

Thanks,

Tom

MT said they would be shipping our order next week. I am guessing that means Friday, January 14 unless they have problems.

First:
"Dual chain 802.11n and Nv2 TDMA technology help to achieve even
200Mbit real throughput speed."

And after:
"One 10/100 ethernet port"

Why can't you write simple: 100Mbps full duplex.
But its the same marketing blabla like at ubi.
100Mbps full duplex != 200 mbps real speed.

200Mbps real througput is siple not true.
I wish if it was.

In a real network DL/UL ratio is at least 3-4.
Real 200Mbps would mean 150Mbps down and 50Mbps upload at the same time.
That would be a real 200Mbps for eg.

Question: When will it be true? Mean when can we get a GE port on such a device?

Good product!!!

inside

Noble idea/product but I can't really see where i'd have much use for a 16dbi antenna especially in the 5ghz range.

Ill hold out until a 23dbi+ version comes into existence.




Also, whatever happened to 2.4xx Ghz ?
Are we to expect some new products in the 2.4Ghz band?


nonetheless, good work mikrotik.... at least you guys are somewhat listening.

It's got a high powered radio in it, when you put the antenna and tx power of mid-range data rates together you end up with about 8w's E.I.R.P which is nothing to sneeze at

16dbi antenna works well up to 5km

What is the mounting system like? Any chance it has uptilt / downtilt adjustment?

Why USB on a CPE device that already has ethernet? What is your thinking on this?

a small 3G usb modem perhaps

What is the mounting system like? Any chance it has uptilt / downtilt adjustment?

like you see in thr picture a few posts above. no tilt adjustment, just strap to a pole.

Hey NZ monkey - the sky mounts don't work very well if you need to mount them to the apex of a building, or need to get 2m of height But I suppose all things considered that could work very well in this situation

Can someone from MikroTik team confirm that Flashfig will work on SXT out-of-the-box?

Rafał, yes it should work.
Before you login to the MikroTik RouterOS for the first time, Flashfig should work.

Great news then. Few past versions of bootloader had problems with Flashfig IIRC. The problems were: bootloader not configured to use flashfig for the first bootup and flashfigged config file wasn't applied.

I hope those problems are fixed for SXT device already.

Question: When will it be true? Mean when can we get a GE port on such a device?

Sorry, Normis. Can I get answer for this question?
Thx, Peter

i dont think that anyone will be interesed to put gbit on a cpe device. It will rise the price of the device. Maybe on some expensive products...

My opinion is that gigabit interfaces Are very needed even at 20mbps traffic. I hope 100Mbit chips are not manufactured any more.

Gigabit for 20 Mbps traffic? You must be joking. Would You buy a Mercedes S-Class just for driving 50 meters to local store for a bottle of beer? Think it over NetworkPro

Yes, its true, that it is a cpe - originaly.
But now the only "one-piece" device of MT.
The concurent company's N****bridge device is also a cpe, but quite good for short pp links.
This new routerboard can be great for short range (<4km) pp links too.
For example if I have a center tower in a city and soma smaller towers, I must deliver there wide banwith, if
I use mimo sectors there.

If you thnk about a new product, you must not see the past, but the future.
On micro now we have to offer 10-30-50mbps access for customers.
Thats why we should forget 100mbps etherenet on such a devices.
As Networkpro said before.

Normis, I'm on your side. This is a great product, the first step in hearing what the market is about in 2011.

The question was about, that when will you build a GBE high performance "one-piece" device?

Thanks for answering.

Update: durig my post Networkpro's last comment dissapeared. What happenned?

My last post was too sincere so it was not meant to exist in this world. (as per moderator message for off-topic)

As I always say - my personal choice is Gigabit because of better performance and future possibilities and just because it's better then the rest.

It's on the web page now:
http://www.routerboard.com/index.php?showProduct=108

My previous que. esd protection the ethernet port or ground poe adapter?

As I always say - my personal choice is Gigabit because of better performance and future possibilities and just because it's better then the rest.

Let's say that Fast Etehrnet chip costs $0,6 and Gigabit chip costs $6. Sorry, but this is just stupid and wrong. Paying few dollars more for something that should not be there.

And as I always say - Those are low cost CPE devices. Not super-hiper-mega-ultra-uber-great-and-all-the-time-shining expensive devices for heavy duty usage.

Edit: One more thing. I agree that some day Gigabit ports will be... well, just standard. But this takes time. I think 2-3 years minimum. Then. RB SXT will be legacy hardware and something new will come. And for today standards and nstreme v2, where 200 Mbps can be achieved (100 Mbps per side) Gigabit port is just too much.

Super-hiper-mega-ultra-uber-great-and-all-the-time-shining devices for heavy duty usage

Don't worry, we will make those too, when time comes Stop fighting, enough with the off-topic.

Ok, my question is still the same:
When will we see thoose "Not super-hiper-mega-ultra-uber-great-and-all-the-time-shining expensive devices for heavy duty usage" stuffs?

If you built this device for 89 bucks, why can't you built an other one with GBE and a bit better mounting parts for eg. 130 bucks?

If any MT guy read this, please answer, if its possible.
Thanks. P.

Simple. They (and most of other manufacturers) build most versatile devices for MOST of folks. The rest is just a few of them.

Thanks, but I prefer MT's answer.
(I think if someone thinks that thoose stuffs are not needed, that one is a newbie on this market.)

Thanks, but I prefer MT's answer.
(I think if someone thinks that thoose stuffs are not needed, that one is a newbie on this market.)

I'm sorry but MikroTik doesn't comment on unreleased future products. Yes, we do have other new products planned.

Its accepptable. Thanks for the answer and keep up the good job.
I think this product line gone be very very usefull.
Thanks again Normis!

good job mtik

my ask for mikrotik :

make such client device what is cheap possess , and this device change ubnt product's.

and if make this on 2.4ghz .it's be very nice

Normis: What type of antenna is inside? This is a printed circuit board (something like UBNT) or Short Back-Fire? http://en.wikipedia.org/wiki/Short_backfire_antenna

Or?

PCB. User manual is now on the site, it has more information on the insides of the SXT.

Wonderful!

How can we tilt up antenna? Our CPEs need always aim up...
What about grounding?

there is a grounding connector behind the door, the default mounting bracket doesn't move, so you will need some adapter to be able to tilt. Some additional details are in the new manual: http://www.routerboard.com/pricelist/do ... ile_id=273

Awesome! I hope your factory is pumping out units 24/7.

Some people will always find something to fault, never anything good enough...
If you need Gb ports and 29dBi then build your MT unit from scratch and leave the rest of us 'noobs' to be happy with the SXT.

B.T.W. it is good luck to send large quantities of new products to South Africa...

One question to prove my noobness, how to make PtP link with level 3 licenses? I thought one side need to be ap-bridge, otherwise how do they associate?

Ekkas

Mode "AP-bridge" is needed only to connect multiple clients to it. Mode "Bridge" is used to connect only one client, making a P-t-P link.

Although it is documented the frequency range 5.17-5.825 GHz. Can SXT go beyond the documented range? I mean from 4.9Ghz to 5.9Ghz

Yes, you can set it to other frequencies if your country allows it, but as the SXT has a built in antenna, there will be no use to do it, because antenna works only in the specified freqiencies. If you use other frequencies, the performance will decrease drasticallty. It's not possible to change the antenna, or connect another antenna. The device is a one piece kit.

Has the antenna actually been tested for it's gain out of ISM bands? Often antenna's aren't and perform quite well, We've seen off the shelf 2.4ghz antenna's operate from 2.3ghz to 2.75ghz with only 1-3db loss of gain

Hi Normis,

I always smile when I see or hear someone from Mikrotik say that "it's not possible". I'm not sure if that phrase comes from former Soviet influence or if it is from something lost in the language translation to English. I have heard it numerous times from different people at Mikrotik. I think your true meaning is that "it's not practical".

When you tell someone that it's not possible, you are offering a challenge for them to prove you are wrong. I'm already thinking about removing the PCB and installing it in an ARC Wireless enclosure with a 24 dBi dual pole antenna or connecting it to a .9 meter dual pole dish.

When you say it's not practical, you are telling us that it does not make sense as it was not engineered for that purpose.

Tom

Tom

Why would you pull it apart, what advantages does it have over a RB711A-5Hn-M or something along those lines.

The device is soldered together with the antenna. You can try to rip it apart, but it will void warranty and there will be no use to do so. This is not just a RB711 built into the case. It's a completely new product.

Just out of interest, will it also use Mipsbe CPU architecture/packages?
Does it come with heavy-duty UV resistant cable ties for pole-mounting?

it comes with a metallic hose clamp like this:
you can see that it has the Atheros AR7241 CPU, so yes, it's a Mipse-BE system.

what the diffenrece between AR7240 and AR7241 ? the MTU ??

what the diffenrece between AR7240 and AR7241 ? the MTU ??

yes, among some other things.

What I like
------------

1) it's a "one piece" CPE (FINALLY!), better than collecting pieces around the globe and with a stable quality from the manufacturer. In the past we had some horror stories when the integrator was changing the "internal pieces" without telling us
2) it's a good price range
3) leds are nice and helps with not-so-smart installers (like on the "well known other manufacturer's" device)

What I do not like
-------------------

1) it has not a good mounting bracket, I would prefer something with a tilt INCLUDED in the box
2) the antenna has a too low gain, 16dB is not enough in many situations

Nice device!

It's got a high powered radio in it, when you put the antenna and tx power of mid-range data rates together you end up with about 8w's E.I.R.P which is nothing to sneeze at

A high power radio is no substitute for an adequate gain antenna.

5 GHz CPE should be no less than 20.

The cost of going to GigE is trivial, but the need for GigE on a $90 device is suspect. If you need that kind of throughput, use a dedicated RB.

Higher gain = Bigger Antenna.

Size matters.

Higher gain = Bigger Antenna.

Size matters.

Indeed. However, a 20 dB antenna really isn't that large. Antenna gain improves transmitted and received signals. It also reduces the amount of noise it hears and the noise it inflicts upon others.

Normis: we have the first photos of the inside. It looks quite cheap

honzam what is cheap is your camera take a picture in the sunlight with a new photo camera and upload that.

honzam what is cheap is your camera

Lol!
Make the punishment fit the crime.

I couldn't agree more.
I hope at least somebody will release an affordable accessory to fix #1 (RF elements, I'm looking at you)

You have not yet mentioned the excellent port-to-port isolation of the SXT antenna. I'ts -30 which is better than any competitor. This number is just as important as the gain, and helps with improved speed and performance.

The 16dbi antenna gain seems to low for me to, but we will see how does it work "in field" maybe the big power will compensate when creating p2p links with two of SXT's

For now I must say that this seems like a good product, i can't wait to test it

I hope that mikrotik is going to make a version with bigger antenna or to sell a standalone RB from SXT, because for example for our CPe's we are using 19 or 23 dbi antennas and anything lower than 19dbi we can use with maybe 10 - 15% of our customers so for now(without having a piece to test) SXT's seems like good p2p link solution for us.

The only thing that's I'd suggest, apart from the tilt bracket is to maybe release a future version with a dual-pol dish built-in instead of patch panels, similar to NanoBridge.
That should give better gain and be great for P2P & CPE, especially everyone that need higher gain.

But I'm very happy that MT is touching this part of the market, it's a very,very good start!

or to sell a standalone RB from SXT

Why not RB711? Or do you mean something like a UBNT Rocket that come weatherproofed?

Dual chain/polararization and 26dbm 711 does not have any of this

Finally i Have The SXT's in my hand.

After testing and comparing with RB711 + 19dbi Box antenna(Panel type) it seems like the SXT antennas are exactly 14dbi.
As for the antenna I was expecting this so I'm not surprised/disappointed.

But I was expecting that the case will be useful outdoor, but it seem not.(At least at our climate )
After simple testing it will not stand any rain, especially when it will be tilted down:/

Could you describe the test that you did and the results please.

Yeah seems pretty fail if theses things can't be used in anything less than a desert!

Could you describe the test that you did and the results please.

I was testing by connecting to the BS ~100m clear view away.
It was no "N" with NSTREME1, I was comparing between RB711 + 19dbi panel antenna.
The 19dbi antennas are made custom for us and we are pretty sure about quality.
The signal level was 55/56db for the 19 and 59/60 for SXT.

We are going to test it on dual polar "N" + Nstreme1 BS, and P2P links but the weather isn't good for such tests now :/

Our supplier did some simple test putting SXT's under "shower" and it did get filled up with water.

Could they have sprayed too much water from the wrong direction to the unit? What was this test exactly?
If you are going to claim bad design, I suggest you post a high res video of the test and results.

Could this be easily fixed? By some holes being sealed with silicone paste to prevent water getting in, in the same test? (mind that some holes are there for a reason)



It is possible that your antenna was better than the SXT built-in one in some way.

Could you please test actual throughput, bandwidth test results comparison between the two?

You know how it goes, tests have to be properly documented and shared and often tests have to be done multiple times to try and deal with random circumstances that may have been overlooked.

Thank you for your cooperation.

thanks mikrotik team i cant wait the get hold of them as i will make good use of it
maybe next will be a 19 or 20dbi sector type device.


as right now i use rb800 or 433ah with ubuquity sector dual for my setups with a bit of modification

it works well

the default mounting bracket doesn't move, so you will need some adapter to be able to tilt

Congratulations with an exiting new product MT!
I know people are nagging you for everything, and a lot of it makes no sense for a low-cost integrated CPE.
But honestly, you should include an integrated tiltmount in your next release of this. Some kind of two discs with notches, tightened with a wing screw.
From time to time it is necessary to aim at an AP situated on a significantly lower or higher elevation, and it is nice to avoid mounting additional brackets or doing a workaround with washers/nuts behind the mount to accomplish this.
For instance, I have used the Micropoynt a lot, but it also has the same limitation and you should do it better!

Normis, I've disassembled SXT and I'm worried about waterproofness of this product. You've made such tests?
Several people tested this already (well sort of, in their bathrooms with a shower) and the outdoor case failed this test. Water managed to "get" inside.

So, what about such test at MikroTik labs?

An announcement will be made shortly, please hold on, Raf.

Let me know what we do with purchased equipment. Leave the service or do a hole on the bottom of the can? Please issue a statement.

Please contact the seller for more information.

doesnt the tp cable bends alot when I close the cover? is that right? especially when the radius of the kabel is about 6-10 cm.

doesnt the tp cable bends alot when I close the cover? is that right? especially when the radius of the kabel is about 6-10 cm.

10cm radius cable?

the hole fits perfectly for normal ethernet cables. the hole size is 6x7mm and it's OK to squeeze the cable a little, helps with isolation.

no no i men the bendig radius.

We are still preparing the general announcement, we are researching the possible causes and solutions.

Fair enough. In the mean time I'll try to mount the unit under some cover and try to "seal" the cable holes.

To those who have already received their first SXT units:

We have found that our initial pre-production test run batch of the new SXT device can accumulate humidity in extreme weather conditions, if mounted in certain angles. This does not affect all devices, but to help solve this issue, we have instructed our distributors to make an additional ventilation hole at the bottom of the case. If you think that you SXT device could be affected, please contact the seller for further information.

Our mass production version of the SXT devices will not have this issue.

Normis, please post some images where users should make this ventilation hole. Not everyone wants to ask their distributors.

Edit: Added attachment

Hi Normis,

The official modification calls for ONE 4mm hole. From the modification doc, it seems that this is at the bottom of the unit when in vertical polarization. If one uses the device 'horizontally' as per the User Guide (SXTug.pdf) page 7, shall an additional hole be neccessary to accomodate this mounting position or are the other holes enough for draining?

Rgds,
Mark

I received my SXT-5HnD unit this morning. I'm not sure why but I can't seem to be able to power on with the PoE injector included.. I tried to open the plastic door to reset the unit.

Not sure if I received a DOA unit or I'm missing something..

is a dualpol antenna; you don't need to rotate.

Hi InoX,

I understand that SXT is dual pol and have already run extensive tests on the bench.

However, my question stems from the fact that the bracket allows only one way of mounting i.e. to a vertical pipe ONLY.

If the structure/tower/offset bracket you need to attach the SXT to is horizontal, then what?

Rgds,
Mark

If one uses the device 'horizontally' as per the User Guide (SXTug.pdf) page 7, shall an additional hole be neccessary to accomodate this mounting position or are the other holes enough for draining?

I think the purpose of a draining hole is so that if moisture comes into the housing, it can drain out. So however you mount it, there should only be one hole at the bottom (ground, the part where grass grow and floors are) so that water can drain out.

It would be silly to have an open hole on the side of the SXT, inviting water in.

Ekkas

The SXT is currently not meant for mounting sideways (hence the bracket that comes with it), but if you do mount it that way, the other hole is enough. Also, like I said, I hope you will not have to make any holes, as this problem only affects the first few units.

Normis.
Do you have plans to redesign the box? Are you going to add a seal to the box?

Since i don't have a SXT handly, i really would like to know where did the water enter..
More detailed information for us curious people, would be very nice.
I hate to say that doing a cheap watertight enclosure with vertical opening has always been a challenge, that's why i was very happy when MT announced it.
Now i feel a little bit sad.
Did the water enter through the line when the two pieces of the enclosure touched??

Even if it's not that, how is the problem going to be solved in the next releases??

If water enters, we are talking about real water, not just condense. That can damage the electronics inside in the long run, so a drain hole isn't the solution..

my 2cents

hi guys, im planning to use a dish reflector for the SXT I'll buy somes 45cm dish like these

Ekkas

I have been told that the reflectors don't work for dual polarity type devices.

it works on solid dishes, the horizontal and vertical waves, and examples is nanobridge M,

From the STX Manual:

"If you want to overcome certain obstacles or interference by using only one polarization in 802.11a mode,
you can switch off chain1 of the wireless device. When chain0 is used, the device is horizontally polarized
when mounted as indicated in the Mounting section of this document. If you wish to use vertical polarization,
turn the device 90 degrees to that the mounting bracket attachment is parallel to the ground. Chain1 can't
be used separately. Switching off chain1 to use only one polarization can be done in the RouterOS wireless
configuration menu."

So our existing 802.11A network is all vertical, therefore I need to mount my SXT 5HnD's (dumb name!) so the bracket is Parellel to the ground?...
WTF about water and drain holes then!

Also we use a simple wall bracket, like you may use for a Nano, a TV antenna, Satellite dish, etc... (most brackets/poles are vertical did you notice?). But If we want to use vertical pol (most 802.11a systems are vertical), then we have to mount the SXT 5HnD's on a Horizontal bracket/pole, that's not much good for pointing the antenna is it?... maybe the bracket design should have allowed for that, like in the RIC design ? Or better still the software should be switchable Ver or Hor when in 802.11a mode like in the Nano?

it works; thats why ubnt released one for NanostationM

They didn't actually. Some people use 3rd party dishes with nanostations, but UBNT doesn't recommend it. They are making a similar device for 900MHz and 3GHz equipment, but they are changing the design the internal antenna of the nanostations to work with the dish reflector. Regular NanostationM's will not be used.

Ok ok guys...

Lets give Mikrotik (normis and crew...) the benefit of the doubt that this model was just a "test/teaser" of some sort and aren't really serious about stepping into the integrated market.

Lets further assume that they are actively listening to the majority of users in hope they will come up with a product housing similar to what the "competetion" offers. I.e. sensible housings/Higher Gain Antennas/Models with a single N Female connector,Models with integrated swivel mounts ... that's all i've gathered really... I mean can it be that hard? - We are willing to pay for it, just make it. I for one am sick of assembling units and essentially mix and matching.

Since i don't have a SXT handly, i really would like to know where did the water enter..
More detailed information for us curious people, would be very nice.
I hate to say that doing a cheap watertight enclosure with vertical opening has always been a challenge, that's why i was very happy when MT announced it.
Now i feel a little bit sad.
Did the water enter through the line when the two pieces of the enclosure touched??

Even if it's not that, how is the problem going to be solved in the next releases??

If water enters, we are talking about real water, not just condense. That can damage the electronics inside in the long run, so a drain hole isn't the solution..

my 2cents

I have installed several of these. MT has not confirmed this, but I think I understand how water has been a problem. The SXT has two drain vents on the back edge. One is on the bottom. The other is slightly higher on the right. If you install the SXT pointing down, the vent /drain holes won't allow the water out. So you can end up with captive water inside and about 10mm deep. Fortunately, the PCB does not extend to the bottom of the case so it should stay dry. By drilling the additional hole where MT instructed, you are allowing the water to drain when the SXT is pointed downward.

Thx roc-noc for the answer..

Do you sorted out how the water entered in the first place??

Any polar diagrams of antenna radiation available yet? No good having a 16dBi antenna with many small sidelobes all over. Antenna design is an important part of the design of the entire product for me.

Come on... We are talking Micro electronics here...
PCB tracks with 0.1mm clearance, Sub miniature components with sub mm dimensions.
Up to 27VDC (boy does DC track!)
There should not be any water or condensation in the same enclosure as a routerboard. Anyone want to disagree with that?
Breathing Holes = holes to let water out...Water that should not be there.

To use it with V pol you have to mount it Horizontal, says the manual, but in this forum Mikrotik say it is not intended to be mounted horizontal.
If you do mount an SXT Horizontal the "breathing holes" will be on the side, not at the bottom, what then?

The SXT has good enough performance/price for short range installs, but the thought of installing 100s of these as CPE scares me to death.

BTW:
Can anyone clue us up on CE complience? I see no mention of it in the documentation or on the units I have purchased from my local european authorised reseller.

Haha. Bla bla. Look at the success stories MikroTik has. It's still better than anything.

Oh please azg... pfftt
Go moan and complain somewhere else.
If you don't have constructive critisism and just want to vent your inner unhappyness, do it on facebook.
We are loyal MT followers becase their routing software is for our purposes the best.
Sure we moan sometimes, for for good reason.
I think this whole issue is blown out of proportion. Do you really believe that MT did not do any testing?
Even if the first batch has a problem, I'll be happy to drill a hole, use some dreaded silicone or whatever, as I'm confident that MT will sort out the issues.

2) manufacture it in quantity

If you read the whole post, you'd see that it would not be an issue for the mass production models.
If you bought one and it got damaged, then complain.

I struggle to think of a single outdoor's electronic device that doesn't have breathing holes of some kind. You need them for simple changes in airtemp, In high humidity environments if you seal the unit during the day at night water will condense out of the sealed air and onto the board.

So unless your CPE is hermetically sealed with an inert dry gas in the air space within the unit you will always need a way for water to get out

I agree. Think of it as "breathing holes", not "drain holes". Pshycologically it sounds less apocalyptic.

The modification is a "drainage" hole.
The SXT already has two sets of "breathing" holes by design.
The front of the enclosure simply clips on without any seal or gasket the total length of which is 42cm.
The Cable entry cover also has no seal or gasket the edge or which is 17cm long and holds in position with an open clip (like on a nano).

So the enclosure already has plenty of "breathing" opertunity.
In all the SXT has 59cm of unsealed edges, two sets of dranage holes (7 holes in all), An open clip area and a cable entry hole.

My conclusion is the modification is a "Drainage hole" A hole to let the water out, water than gets in around the front cover and / or the cable enty cover.
Water that otherwise would pool inside the case.

Routerboard recomends a 4mm hole, we know from experence that this is just the right size for wasps to enter and build their nests inside.

A breathing hole is just that.. A hole to let vapor out... The SXT has holes to let water out, Holes to compensate for The fact that the edges of the front cover and the cable entry cover can let water in.

I also know of plenty of breathing designs, but I can't think of any designs that have so many joining edges without any sort of a gasket and on vertical surfaces too.

For good design practice look at the AntennaBox PA19. it needs no breathing/dranage holes.. and has proven to be 100% watertight in over 900 installs we have done.
You will note the PA19 has a gasket and screws to fix the main entry cover. It also has no holes, openings, joins or seals above the electronics area. If you need to change the polarisation you rotate the antenna inside the case, not the case, that way the cable entry is always at the bottom.

Anyone care to comment on the V-Pol issue and mounting a SXT on its side?
Or CE complience?

I also know of plenty of breathing designs, but I can't think of any designs that have so many joining edges without any sort of a gasket and on vertical surfaces too.

My bad. It's official then; I'll call it a draining hole from now on.

Can anyone clue us up on CE complience?

The product is lacking a R&TTE Certificate of Compliance, which means it isn't. (Mikrotik says they are working on it.)

I shall leave it to importers, distributors and users to decide for themselves what that means from a legal perspective in their particular country. But as we are in the EU, we shall not be purchasing or installing them until they are compliant and thus legal.

To come back to the need for Giga ethernet interfaces:

What most people do not realise is that telephony requires a very low ping response time so as to prevent echo on a call. This can be achieved by having giga ethernet interfaces, as every step in the link helps, and helps a lot. (25 years telephony experience)
That means to say that I run only dual N at 130Mbps and more on my backbones even though I only need 10Mbytes for the customers, just to get good voip (G711) PSTN telephony, not only is the echo reduced but the speech quality is noticeably improved in general.

I have about 100 customers sucessfully running on Voip telephony with 5Ghz CPE. So I am quite happy to pay the extra for Giga ethernet interfaces which are not yet here on CPE mikrotik.

What most people do not realise is that telephony requires a very low ping response time so as to prevent echo on a call. This can be achieved by having giga ethernet interfaces, as every step in the link helps, and helps a lot.

When passing 20 Mbps of traffic, a GigE interface does not have any lower latency than a FastE interface.

I make calls to a location 4000 km away, for hours per day, using VoIP with 110 ms round trip time.
There is no echo and 110 ms is certainly not "very low ping response time."

The serialization delay is 10 times lower on a gigabit The delay could be as much as 10 times lower. I test this with fast ping when under big pps load.

The thing is that when you build a MAN - you can see and feel the difference if you used 100mbit vs gigabit. Going through multiple switches under load amplifies the effect.

And you have usable VoIP call, not a perfect one. 110 ms delay could lead to the people talking one over the other etc. And when you include the buffer delay, codec delay etc.

That's why we like g711 over 0ms - 10ms ping to called party

And with wireless - if you don't have proper nstreme set up, you get those damn 10-30ms pings with jitter under load

I have trouble with setup SXT works wery slow...

trying with bandwith test 4-5mbit/s try with iperf the same ... where is problem hiding?

it comes with a metallic hose clamp like this:

546190.jpg

you can see that it has the Atheros AR7241 CPU, so yes, it's a Mipse-BE system.

That clamp is very big. Minimal diameter is cca 1.9 inch (5cm). We use smaller console for clients. For SXT is small consol enought.But this clamp is made for satelite console.

To use it with V pol you have to mount it Horizontal, says the manual, but in this forum Mikrotik say it is not intended to be mounted horizontal.

Hi Nick, long time no see or hear fm you! Also fed up with using nanostations?

Polarity depends on the chain/antenna you enable in the router, its a dual pol antenna. So mount it the way MT designed it for (and that is vertical as I can see on in the manual) and use the chain for the V-pol antenna in that case. That should work imho.

open the latch, there is a reset button. keep it pressed while booting and it will run netinstall server. follow netinstall documentation from there.

Works nice, pressed the reset button after boot. The second-inner led started blinking after a few seconds. Released and the antenna rebooted after a few seconds. Then appeared on Netinstall. Restored image correctly. Thanks!

A lil question :

it's normal that with 2 different sec. profiles, 2 SXT can comunicate ???
not for me .

here the specs :
SXT n.1 :

routerOS 4.14
mode : bridge
band : only N
wireless protocol : NV2
security profile : default

SXT n. 2 :

routerOS 4.14
mode : station
band : only N
wireless protocol NV2
security profile : profile1 (wpa2 + aes)

with theese configs i can ping and make a BT .

junkie, please look at this section in the wiki on the security in nv2:

Good one!
MT sales guys now are worried about higher end product sales...
Did you use longer rods, so the SXT is in focal point or it was about the same for SXT or the transmitter head?

i have 3 km ptp sxts
and there is high interference cause a high packet loss ( sometimes more than 10% )
currently I'm using super-channel with 10MHz CH BW
what is the best thing i can do to avoid the interference

khalid:
locate interference sources (look around, or use freq usage) and try to physically separate
(put Your device behind conrete elements on rooftop, or use shielding)

Hi Guys, please for your help...

I'm trying to deploy a new implementation with a central AP and respective connected clients on 5ghz band.

I bought an 433UAH and a R52n miniPCI. Clients will be SXT CPEs.

Furthermore I choosed to buy a MIMO sector antenna with dual Horizontal & Vertical polarity (HV).
Same munufacture produces same dual polarity sector antennas with HH & VV polarity.

As I read from SXT manual it supports dual polarization antenna too that's why I bought the HV sector.

Question: Is my approach correct? If no, which is the recommended polarization for SXT? HH or VV?

wolfeyes: SXT is dual pol by default, so should work with your MIMO sector.
Additional info: chan0 is Horizontal polarized - so if You want to connect to a Vertical (only) sector,
You have to rotate the device by 90deg

Hi,
can you help me?
one provider in my area gives such equipment to connect to the INTERNET can you explain me in simple words will it work ok if I have a cottage and the provider's antenna is 3-4 km away what speed will I get? how will it works?

Hello
Let my introduce some Ukranian Reflector Antenna for 5 SXT from my factory SS&T(http://www.sstua.com)
It converts 25x25 of built in antenna to 5x5 degreese and let increase work distance up to 7km with out any modifications.


Price 40 Euro

just WOW

My ptp link with SXT stop passing data. I've changed nv2 with nstreme and is working now. Tried to changed back but after ~10sec stop passing data and then work again, and so on. Tried 4.17 and 5.2. Link had worked fine for about 2-3 weeks and there were no modifications.

Besides turning the SXT sideways 90degrees what else do you need to do to make a SXT connect to a vertically polarized 5.8ghz omni antenna attached to a XR5 on a RB433 on top of a 200ft tower about 1/2 mile away?
It sees the signal with SNR 34 to play with - it is set to "station bridge" and/or "bridge" and neither will connect. Of course NV2 with TDMA 3 and QueueCount 5. No security turned on on either side.
The omni has 4 other "standard" XR5 or SR5 boxes connected to it at 20mhz Freq 5785
(btw - the v5.2 series kick ass on ptmp! still a timing issue with 2.4 802.11 legacy stuff tho but otherwise a GREAT product!)
Am I missing something?
Thank you,
Rod

All information is in the manual!
Chain 1 can't be used separately. It doesn't work like that.

mounting bracket can't be turned, you need a horizontal pole or some DIY adapter. We are working on new brackets.

OK, that is cleared, but what will come to the water exit holes of the unit? By turning the unit these will effectively become water entering holes and thus making that type of action fatal to the unit.

no, if you turn according to manual, all holes are still pointing down.

this image shows both polarizations and holes. as you see, no matter how you mount it, none of the holes is pointing up. don't worry, we have tested, no water can enter in the sideways hole even if you point a waterhose at it

We are working on new brackets.

Normis, you SHOULD make a tilt bracket for this one!

Thank you.

Yes, we need another bracket, but only to make it tilt up or down! That's it, no more talk about 90 degree turn or so. Just tilt up and down and the unit is perfect.

Exactly!

if the other end is v-pol only, you should still be able to connect even in normal mounting positions and with both chains enabled.

as it is noted in the manual chain0 should be always enabled as if you disable it then chain1 would not work correctly.
One option that you can try is to disable the TX for chain0 and leave RX enabled for chain0, but still we recommend not to disable chain0.

Is there any reason why it is better to leave chain0-tx on while not in use?

you read it wrong, the suggestion is to leave Chain0-RX on. This is because of a hardware limitation. If you don't leave it on, Chain1 performance will decrease.

ok, a simple question - why do you need to disable any chains ?

it works perfect with all chains enabled.

ok, a simple question - why do you need to disable any chains ?

it works perfect with all chains enabled.

The only reason i could see is to conserve spectrum noise if you are using a single pol vertical omni, and using the Rb/SXT to connect to it.

In this case always just disable TX on chain 0 and leave RX on chain 0 ON and then check both RX/TX for chain 1.

Works great, uptime for weeks on end! and still get 150/150 rates without issue. Why even bother with rotating it?

Maximum output power does drop to 23dB in this configuration, but not a problem....

-Brad

On the other hand, if you have noise on a H pol on the same channel... then you're forced to rotate...

but thankfully 5ghz is pretty clean most of the time! (in my areas)

BTW - Ukrainian antenna guy -- AWESOME! too bad i'm far away in america, i would have to try some out!

ok, a simple question - why do you need to disable any chains ?

it works perfect with all chains enabled.

If you have to limit power due to regulations you can decide
to spread power over 2 chains or use double power on one
chain.

Finally someone that understands where I'm coming from...

For single chain operation in V-pol, ONLY Two options:

1. turn antenna 90deg and use Chain0
2. don't turn antenna and disable Chain0-TX
( or 3. leave everything as is, it will connect to Vpol devices by default )

Recommended to use option 1.
I have run out of explanation methods
