LHG 60G experience

Lakis · Wed Nov 07, 2018 3:21 pm

Thanks for fast replys. You are deploying that tool for us, so you really should expect us to use it
But as we know from other installations and devices that can test there throughput we never expect such tests to be real. So yeah, we tried actual traffic - maybe it was a misspoke here. We tested file transfer with a folder and round about 70 GB of Files with different sizes. Also we had iperf running which was also match with our tested data.

Totally forgot about to mention the version we are using: We run them with 6.43.4

I think we will have a look on our alignment again.

@server8
Is this a set of 2 or do we need to order it twice?

One of your ethernet may be connected at 100mbit speed.

Honzam how is 4173m link, any luck with the rain is it stable?
Thanks.
No you will need backup

What about 3km link, if I use 66Ghz do I need backup?

I am a bit depressed - should have checked that myself.
Your expectation is right - Peers interface is however set to 100MBit/s. We'll investigate that when we check alignment...

I tried to use align option for alignment the links and update devices to beta version and it's seems broken... when I use align in cli mode rssi and signal change so rapid for ex 50- to -58 but so quick when use monitor its better. which one should I use ?

and what should I check first while align, tx-sector-info ? or RSSI ? or Signal ?

too much option on it

Thanks

blue · Thu Nov 08, 2018 6:13 pm

I don't use align for same reason - to fast and all-over-the-place update of data. Use normal monitor, but be patient. Move lhg slightly and then wait couple of seconds. I look only at RSSI...

Hi,

To all who have aligment problems!

Use this method and You never miss:

https://www.aliexpress.com/item/10000m- ... a4f512def4

1. Install just the LHG mount

2. Allign the mount with the laser

3. Install the dish to the mount.

4. Enjoy

antenna pointing is very difficult, as the signal is updated with a delay.

Apparently you do not direct the antenna. We previously worked with SIKLU so there is experience.

The main thing that would be direct visibility and accurate guidance. There are more people who have if the link and 4 km.

We should be getting up to 70 GHz in the UK , will the hardware support this i wonder? There is no "country code" option at the moment. 70GHz would be nice to use.

Hi!

Today, I tried to install my first LHG 60G - with not so much success...

399m, perfect LOS. No rain.
RSSI is only -48 NO MATTER, if it is really centered or no, NO matter which frequency. I could not get more than -48.

BUT: rx-phy-rate is changing all the time from 2.3 Gbps to lower values to "connected: no". tx-packet-error-rate is showing crazy values (between 0 and 2000%).
I am using RouterOS 6.44beta28

Can you give me a hint, what was my fault?

EDIT: Just disabled beamforming (tx-sector=36). Now, the link is stable at 2.3 Gbps phys, but still at -47 to -50db. Did you ever see better RSSIs?

Thank you
Stril

Hi!
I am already using this kit on both sides, but its really strange:

I can see a wide window, where RSSI is about -50db! I just cannot get more than -40 to -50 - no matter if "perfectly alligned" or not.

One more, strange thing:
With 6.43.4, PHY-RATE is sometimes going down, IF there is no traffic on the link. If I start the bandwidth-tester, phys-rate is stable at 2.3 Gbps. Without traffic, it is fluctuating...

And what kind of RSSI do you expect at this distance?!? o.O

Stril · Sat Nov 24, 2018 9:07 am

With the dish (LHG60G)? Should probably be around -30/-35. At 400m, it should be around -45 and at 1km, -55 (with channel 4). With channel 1, it's probably going to drop to -55 for 400m and -65 for 1km.

I found that post and thought, -50db is not good for 400m...
If -50db is o.k.: Do you have any idea, why I do not get a stable tx-phy-rate, although RSSI is good? I tried different channels, beta-firmware and stable-firmware, with and without beam-forming.

I am also confused, that RSSI is the same - no matter, if I align the antenna to center or some degrees left/right and that it is not very stable. It goes up and down all the time for +- 2-3 db

You need to know that LHG60 has an Antenna array not only one,
So there Are more positions to get max RSSI

The fluctuation you see on data rate , you see the same on all 802.11ac Radios from MT if you not use the Link.

Those values were based on theoretical values for another device and adjusted to LHG based on real life experience. If you have more than -50dB, that's fine. The line won't start to drop before around -70dB so that's plenty margin.

LHG have beam forming so they don't need to be exactly aligned. Also, during the beam forming, values are going to change. You have to wait many seconds for the ligne to stabilize when you do alignment. If you reboot the devices, you will often not get the exact same values.

But do you have any idea, why the phys-rate is not stable although RSSI is good?

I tried it with and without traffic. After some time of traffic, phys-rate is mostly 2.3 Gbps but not always. Do you see drops without traffic?

...and what about the error-rate? What do you see here, or are most of you using the stable firmware?

Thanks for the congratulations

Link was deployed today. It is too early to say anything about it, but 5GHz AC will be backup. I didn't had adequate equipment for test, and btest is useless these days. I need another day without wind to finalize aligning. For now only one test user is using/testing it.

BTW this link is a part of two p2p links to span over 6km. Few weeks ago we tried that distance but it didn't work. So, now we have 4332 metres plus 2679 metres.

So it is to early to give you guys some results.

As You can see, both links are working on 66.000! On the central location. antennas are almost back to back, and it looks like it doesn't bother them

I tried shorter link at 64ghz, but connection was not stable. I assume that is misalignment related.

Well its just for testing purposes, nothing else. Its not even stable....i was just curious how far can it get. Usable distance with pair of LHGs is about 1800m at 66GHz or 1400m with 64,8GHz. Stable in rain about 50mm/h. But for now we need protective cover for whole LHG because the grid of LHG is nicely holding snow and kills every longer link.

Hello

A colleague tried to install the Wireless Wire Dish kit (RBLHGG-60ADKIT), from mainland to an island. Mounted at 3 and 6 meter height, 700 meter over a lake, clear sight and so forth.

Also tried a different kit, same results. Default configuration, but no connection at all. Kits works without problems if next to each other. (ROS within 6.43.*). Used a couple of hours trying to align them with no success at all.

0.7 km with 60 Ghz should give maximum 0.93 m radius on the freznel zone ?
(Freznel zone calculator / formula).

How accurate must the alignment be for a successfull link to take place?

Other than alignment issues what could the problem be?

I would expect to see contact/link after trying long enough, even just for a short while ?

Next try we'll keep these tips in mind:
- Better mounting kits and/or lasers
- Disable beamforming: /interface w60g set 0 tx-sector=36
- Using CLI alignment (quicker/too quick): /interface w60g align wlan60-1

from our experience, the most important thing is to put a good amount of traffic over the link during the alignment. If you don't, the readings are not updated fast enough. Even in alignment mode.

If You could try downgrade to 6.43rc17 and see if it helps, I stumbled on very similar situation and downgrade to rc17 works like a charm.
And there is few similar situation in my deployments that rc17 works with stable mcs8 when newer fw wont even connect.
So If You would confirm rc17 as a solution I wouldn't feel alone

paulct · Tue Nov 27, 2018 8:20 am

Yup also using the latest beta. On two separate links of +-1800m and 2000m cannot even make a single link. Using 64800 and 66000. You would think after aiming for a while there would at least be a connection - a bad one at least.

blue · Tue Nov 27, 2018 8:32 am

Yes, You have to wait a little (a lot) for link to establish. Be patient. First, connect devices in lab conditions, and after that take them to the field. Be sure to use 64800 or 66000. Aiming of LHG is very critical since it has only 2°. That 2° is very different from 5GHz. 60GHz have instant cut-off when You misalign the link. Once again: be patient. And put some traffic between devices while aiming - it would help a little (thanks to ryny24 for the tip).

And one last thing - I am using latest beta (6.44beta28) on all of my 60ghz links...

Stril · Tue Nov 27, 2018 9:57 am

Hi!

Aligning is a real pain compared to other 60G-devices... I was using two Bridgewave-Links which could be aligned with a multimeter - easy process.

The LHG 60G are crazy:

- Without alignment-mode:
It takes 5 minutes! until the signal gets stabilized! RSSI dances up and down within the first 300s. Then, it is getting stable.

- With alignment-mode:
Signal varies A LOT! I wrote a script that averages the RSSIs of the last 10s to be able to see anyhing...

- After every restart of the link, it shows another RSSI...

I am using the precision-bracket, which is expensive but GREAT, but as the signal is not stable, its hard to find the right position...

Tue Nov 27, 2018 12:25 pm

please check if scan-list on "station-bridge" device includes frequencies you are trying to use. Alignment needs to be very precise for connection to be established.

Hi!

Can you tell me, what kind of grounding you are using with the LHG60?

Option 1:
Use shielded patch-cable and a surge-protector like the UBNT ETH-SP-G2 to ground the patch-cord.

Option 2:
Add second cable to the antenna with grounding-cable

Option 3:
Option 1+2

Thank you for your hint!

blue · Tue Nov 27, 2018 10:15 pm

Wherever I can I use second grounding cable in combination with Schrack outdoor s/ftp cable. Anyhow, for me grounding is a must - regardless what many others are telling.

Yes. I suppose there will be less gain, perhaps 6dB less, so I could suppose a reduction of 50% in distance, 1500m-> 750m. In 750m there is also less fading, so I could suppose that a link from wAP 60G and one or more LHG 60Gs over 500-800m could work at least the same than a 1500m link composed by two LHG 60Gs. Is it right?

Depends on needs for Link,

with WAP to WAP wo go to 100m
With WAP to LHG we go to 300m
With LHG to LHG we go to 600m

WAP with 150m we see downtime in hard Rain, also with LHG at 800m

SpanMG · Fri Dec 14, 2018 9:13 am

Friends, I ask for advice.
It is necessary to make a link to 250m. Traffic is assumed not much, up to 100 Mbps. What is better to deliver, LHG-LHG, or LHG-WAP
It is required in 60G, because. 5GHz is very noisy.

mistry7 · Fri Dec 14, 2018 9:38 am

LHG ist 50€ more, and for this your link would be near 99% available......

SpanMG · Fri Dec 14, 2018 10:08 am

The price in this case is not very important, because the difference is not big. I understand that if you put two directional antenna LHG, then accessibility will have to be 99.9999%
But what will be the availability if you put two WAP or WAP-LHG

What if you go a bit out of range or a little bad weather hits and u dont have 1gb anymore, like have 800mbit, 5ghz would push that 200mbit back giving you full 1gbs again, doesnt matter if u go over 1gbs combined 60+5ghz during ideal conditions which would saturate your gigabit ethernt port, its about quality of service and failover.

Thats one example, besides why not use both links at the same time?Instant fail-over without interruption, isnt that the general idea?

It does look proper for the job and it is actually half price from the 3rd party one. Has anybody got any experience with it? Is it any good?

I have 5 different PtP links that I would like to upgrade to 60GHz.

The distances are:

40m
160m
185m
460m
1280m

There is never any snow and heavy rains are rear. I was planning to use LHG60 wireless wire dish for all of them but somebody suggested that the dish would not be good for the 40m link and that I should possibly use the wAP60G for the short links.

What is the problem with using the LHG60 for shorter links? Oversaturation of the receivers? If so, can power be turned down? I would prefer to use the small beamwidth of th dish than the very wide beamwidth of the wAP60G if I can avoid it.

My only requirement for all these links is max throughput and as close to the quoted gigabit speed as possible.

Any suggestions from people with experience on these shorter distances?

Thank you in advance

server8 · Thu Jan 03, 2019 3:25 pm

No problem for the short one use a WAG60+WAG60, for the middle two use WAG60+LHG60 and for the last 2 use LHG60+LHG60

if the 5 links are on the same tower remember that 64800 MHz overlaps partially 66000 MHz so you have to separate LHGs in angle and distance.

Use higher channel for longer links

aisme · Thu Jan 03, 2019 9:02 pm

Thanks server8.

The question is why is it a problem to just use LHG60 for all of them? Do the LHG60s do not work over short distances? And what is their minimum distance?

I could not find this info on their specs.

The links are not on a tower but on a roof of the same building. I can have about 5 metres distance from on to the other if needed and they all look a t a different side except two

I think you can use LHG60 without no problem but the wag60 has beamforming antenna with a narrow beam, for the shorter link is easy to install and manage.

For the colocation you have to make some test there are no reports from other users with 5 x 60 ghz radio in the same site.

Please tell Mikrotik that they will do the test on LHG60, will be stable 8000 meters, no way man

Tests in Poland [weather,rain, snow]
LHG60 - LHG60 - max 700m-900m stable on 64800MHz at 1/1Gbps [snow, mainly the rime kill the antenna]
Dish 400 Feeder - Dish 400 Feeder - max 1500m stable on 64800MHz at 1/1Gbps
Dish 600 Feeder - Dish 600 Feeder - max 2500m stable on 64800MHz at 1/1Gbps, we tested 1738meters, rssi -60 so at -69 will be 3000m

In each country will be different; different conditions, different humidity, other damping etc.

Stril · Wed Jan 09, 2019 1:11 am

Hi!

Why do you use the feeder, now?
Your first setup was: LHG with alu dish AND cover. What's the advantage of the feeder?

djvolt · Wed Jan 09, 2019 9:33 am

Full Solution for electronic LHG60
* better beamforming, because the electronic is perfectly center of the dish without any deform
* is possible to make 5ghz backup
* have waterproof gland on the back of the antenna so you can easly dismount from the mast
* mainly made for PtP Links

Alu Dish 400 without the feeder is only a fast solution to help others cheap dismount the grid and mount the original triangle feeder. This helps to do better rssi and reach more meters in rain and snow, secure from the rime, is full hermetic with ABS Cover... Mainly made for PtMP links, but others use this solution also for PtP links.

Alu Dish will always better than original grid.
Alu dishes will always better also in 2,4 and 5ghz.

Differences between ROS 6.43.7 and beta50 are huge so we have a better solution, the rest will do the software from MT... If original LHG60 will have teoreticaly 1500 meters our solution will have x2

You cannot use 66, because is only for >3000 meters...

This is standard ALU without the feeder, with the front cover the snow at this point not kill the antenna and the distance is 2x than original lhg.

No way to get poor signals with alu dish, alu dish is not the plastic grid, alu dish always be better than plastic, aluminium always be better than plastic grid!

As I wrote there is also fast upgrade that make stable link in rain and snow, mainly to protect from the Rime, to get better performance and stability, no RSSI... If original LHG60 do 700meters stable, with alu dishes is 1400, 2 x better distance...

Maybe U must off or use 36 beamforming? Do you know about that?

No tx power at this time.

You can't just make a random aluminum dish and expect it to be better just because of material. There are calibrations done, specifically for the original grid. Antenna design is a precise science, not a form of metallurgy.

marcin21 · Tue Jan 15, 2019 12:15 pm

@Normis, anything solid is better than this grid, especially in weather conditions as in our north countries. I can't imagine what was You thinking designing this particular antenna. Lower windload but possible total death of link due to snow/water/ice cap? You have Dynadish project You could use to achieve much much better product. but You choose grid antenna. So it's not weird that lot of people trying to fix mistakes of Yours by adding covers, alu dish etc.
AND answer is YES anything of casted/forged aluminium will be better than plastic grid just in matter overall availibility of link/year
Do your product more wisely in next release PLEASE.

Indeed. Especially remember that the higher the frequency (hence, the shorter the wavelength) the most precision needed.

The only solution I imagine for the ice problems is heating and/or some water repellent treatment. There are specific PTFE based sprays for that. Or maybe something like silicone based lubricant.

I'm waiting for some snow here to try but in 50 years I've seen less than 5 serious snow events.

Best is to use the heat of the radio/board itself. We see problems with snow on the longer links even if it does not hang to the antenna. Seems to have more influence on 60GHz than rain.

Yes, problematic with the LHG though, I doubt the dish gets warm enogh.

Some time ago I read about problems they had in the Deep USA with LED traffic lights. Being more efficient than the typical tungsten incandescent lamps the things didn't get warm enough and it was frequent to have them covered in snow. They had to add a heating system for the Winter.

Oh and starling droppings could be a problem as well!

I did a quick test link today between LHG60s and distance 167m. The link came up and was connected but I assume it needed further adjustment because the values were all low: MCS 3 and phy-rate 923mbps. RSSI -65.

The frequency was at 58Ghz and just for testing I changed it to 66000 manually on both sides. The link immediately dropped and never came back.

Does anybody know why the link disconnected because of the frequency change?

My 2nd question is what is the favorite/usual method of aligning the LHG60 dishes?

Do you install both dishes and try to point them as best you can to each other until they link? And then go to one side and adjust trying to maximise RSSI, then go to the other side and do the same and then go back on first dish and try to adjust even more and back and forth?

What is a tried and tested method of properly aligning these dishes?

Thank you

Hello aisme

This is that what I wrote some post ago, no way to use RSSI as determinant of connection quality

Please use BTest to align correct link... If BTest show around 900Mbps in UDP or >350Mbps in TCP sesion the link is rock solid stable. You can also use align command, but BTest is the best solution at this moment... Please check always tx-sector information, perfect is "Center" mean 0

I have also this defect on ROS 6.43.7, 6.43.8 and beta50... After disconnect no chance to up the link

Stril · Wed Jan 16, 2019 12:22 am

Aligning with BTest is a very bad idea for a short link in my opinion.

Bad aligned means: Gigabit on good weather, lower bandwidth on heavy rain.
Good alignment means: Always Gigabit
--> You want gigabit on all conditions.

What I do:
- Align "by sight" both sites (should be easy for 200m)
- Optimize RSSI on first site
- Optimize RSSI on second site
- Optimize RSSI on first site

Optimizing means:
- Align-mode
- Y-axis until best RSSI
- X-axis until best RSSI

I did that for a 400m link and it was quite easy.
You can make it easier, if you set tx-sector=36 (center) while you align.

On a 200m link, you should be far below -50dB (I think, about -46)

I've found out that a small amount of radioactivity is more effective. I am testing by fixing a piece of Tungsten-Thorium welding electrode. The beta particles emitted by the decay from Ra-228 to Ac-228 seem to help repel the water molecules from sticking to the surface.

Hi!

I just installed the Alu-dish+ABS-cover (that DJVolt offers) on one side of my LHG-Link.

RSSI seems to be a bit lower with Alu than with LHG-dish (+3dB) on my first test

 /interface w60g monitor 0
             connected: yes
             frequency: 64800
        remote-address: 24:18:1D:63:62:56
                tx-mcs: 8
           tx-phy-rate: 2.3Gbps
                signal: 85
                  rssi: -53
             tx-sector: 36
        tx-sector-info: center
              distance: 395.18m
  tx-packet-error-rate: 0%

--> seems to be ok (minimal more loss, but better protection against snow)

Some things about the Alu-Dish+ABS-cover:
- Alu-dish is very flexibel. When you adjust the screws, it bends.
- ABS-cover is not very precise. I hat to make the holes bigger to be able to use all screws.

Edit: One strange thing:
"Original" LHG works best with 64800 MHz in my setup - With Alu-dish, it is best without beam-forming and with a lower frequency!

djvolt · Wed Jan 16, 2019 6:27 pm

I confirm, please off beamforming in newer versions or use 6.42.11 with smaller tx-power on that distances.

Up to 1000 meters 58GHz, up to 1500 meters 64800.

Update for ALU vs LHG dish:

The ALU dish has a strange behaviour: RSSI is good, Signal ist good, but MCS is unstable!

With LHG-dish, i see a stable MCS of 8 (PHY Rate: 2.3 Gbps). With the upgrade-kit, MCS goes up and down from 4 to 8.

Do you have any other idea, to make the LHG "snow-proof"?

komenski · Thu Jan 17, 2019 9:16 am

I think it's highest time for Mikrotik to properly illuminate some essential features of his 60 GHz products. To date, we do not know the LHG and WAP60g exact radiation characteristics (even in frequency dependence), which is at least unusual and suggests that radiative patterns will not be so nice, but they should not be secret to users.
Further, I believe that this device would necessarily needed mode "align" which are temporarily turned off all functions counterproductive when setting up the connection (beamforming-center or off, constant TX power, MCS, etc ..). Many of the problems mentioned here are directly related to the incorrect setting of both sides of the link and consequent frustration by degraded climatic conditions (I do not think snow).

This is only 400meters, the power is to strange with alu dishes, without limit the power this link I think will be unstable. Please set beamforming to 36, if doesnt help please downgrade to last stable version like 6.42.11 and set tx-power to 5

Original LHG is designed up to 600-800meters that should be still connected while weather conditions are bad...

For Mikrotik: please add option in software where we can set tx-power, MCS and set beamforming...

Its time to do all, because all used waps as sectors and lhg as stations, but it doesnt works properly...

SpanMG · Thu Jan 17, 2019 1:11 pm

Friends, go today, put the antennas on again, until they received such signals.

But noticed a strange behavior of the antennas. When hovering in the second antenna, the first one may fall off, although the signal on it is normal, this happens at that very moment when we aim the second antenna.

Such a feeling that there is some synchronization in the WAP.

Mikrotik has such a GREAT product with the LHG60G, but details are just too "cheap".

A "LHG-60G-PRO" with weather-proof, professional layout and better align-feature would open the doors to new customers for mikrotik. For short links, LHG-60G-PRO could be as good or better than UBNT AirFiber, etc.

djvolt · Thu Jan 17, 2019 11:40 pm

Second is perfect on 64800. Puts full duplex 1/1G.

What would you like to get more on 400mm dishes without set correctly tx-power, MCS and tx-sector beamforming? Nothing else without this parameters.

You can only set tx-sector beamforming to 36 if you have Auto mode...

If you have a time please downgrade to 6.42.11 and test again with adjusting tx-power

komenski · Fri Jan 18, 2019 7:52 am

Explanation is the only one - LHG60g feed overradiates its parabolic antenna by most of frequencies. Probably the influence of the shape of the LHG60g cooler, which acts as the mouth of the waveguide - is to be modified for collar dishes.
In any case, must be set to a fixed tx-sector close to the center (27,28,35,36), auto-beamforming works counterproductive.

Stril · Fri Jan 18, 2019 9:08 am

Hi!

There are just too many variables and modifying the hardware makes it any harder...

I have a 400m link. With lower frequencies, RSSI ist better than with high frequencies, BUT: MCS is unstable!

58GHz: RSSI=48, MCS is going up and down (on stable weather conditions)
64GHZ: RSSI=54, MCS stable on "8"

BUT: that happens with ALU-dish and LHG...

Perhaps, its a better idea to only add a cover and not to change the dish...

I'm using 6.44beta40 and it's working great. Nothing new in the latest beta61...

To short link for ALU

No TX-POWER control... While will be available change this and set properly tx-sector and MCS the link will be extremely stable...

BUT:

Effect
effect of lack of power control, tx-sector and mcs together, but the link is extra stable...

What are the commands to set 66000 and add 66000 in the scan list on the client and AP sides?
Still need these Chris?

Mikrotik 60Ghz CLI commands

AP
/interface w60g set wlan60-1 frequency=66000

With 6.44 beta61

I can not set on STA the frequency list

What is wrong ?

hy everyone,

we use a 60 GHz link in 387m (signal :95, rssi: -54, tx-phy-rate:2,3 Gbps) , it works great, but i do not find how to see "link downs" in dude. I can see a lot of things with snmp, only this parameter i not find.
Have anyone an oid code for this, or just tell me where can i print it out in terminal. Yes i know i can see it in winbox, but it would be great that i do not need always to log in after a heavy rain to see it.
thanks

SpanMG · Mon Jan 21, 2019 10:09 am

Hello again!
Over the weekend, the linkage fell, this time he recovered himself, but the breaks are quite significant 10 minutes to 40 minutes.

djvolt · Mon Jan 21, 2019 11:54 am

On 400 meters? Its impossible or the new firmware is completely broken...

We use 6.42.11 and is extremely stable, also in this version is 66GHz available.

As Strill said I confirm, that alu dishes are stable without beamforming, tx-sector on 35 or 36 mean perfect "center" with proper alignment. No MCS falling, always show 8 and signal 80 on 2100meters.

Any news about different channel width like 1Ghz , 500Mhz and so ?

Thk

lashguti · Mon Jan 21, 2019 10:08 pm

+1 for channel sizes

100mhz or 200mhz steps will be better, at least 500mhz steps. not all need 1gb in ptp and in PTMP ( 8 online ) for sure

For all those who struggle these days with devices being snowed up - available solution of radome covering for harsh meteo conditions:

https://www.wifihw.cz/default.asp?cls=s ... ng&lngid=1

thats veeery good. seems that now somehow option for winter is available.

by the way, my thoughts WHY it accumulates snow. In order to accumulate ice - surface need to be cooled to LOWER temperature than abient static, then if we have humidity and a bit warming, we get ice on it. How to cool surface? easy - WIND, which blows through antenna cells. (: greetings from aerospace engineer

to simplify for who did not got about what it is written, imagine your deep cool fridge and result of the different in temperature you see inside the fridge box.

THEORETICALLY, if antenna to seal with PLASTIC bag from the back side, it should accumulate much less ice/snow

djvolt · Wed Jan 23, 2019 1:13 am

But this is also only plastic, expensive plastic

I finally received the Mikrotik Solidmount precision bases and for those wondering they are very well made indeed. They allow for precision movement in both X and Y axis. I wish they were included in the original package instead of their normal one. I have not used any of the 3rd party ones so I have no way of comparing them but for their purpose they are more than good enough.

When installing the LHG60 dishes I used Ubiquiti TouchCable terminated with Ubiquiti ToughConnectors and using the Ubiquiti surge arrestors. As per instructions this requires a short cable to connect the LHG60 to the surge arrestor. Then the surge arrestor connected to the long run of toughcable and close to source another surge arrestor and another short cable from the surge arrestor to the network switch. Field termination of the toughcable is a royal pain and I would like to minimise it at just the long cable run. Does any body know of a good source of outdoor rated, S/FTP, solid core, patch cords to use?

I've found a company in the US selling toughcable based patch cords terminated with toughconnectors but I am searcing something in Europe and it does not have to be made with Ubiquiti cable as long as the cable use includes a proper drain wire and not just the foil wrap.

Any information highly appreciated.

Finally got my link up! 64Ghz wasn't cutting it but when I've tried out 66Ghz we now have a link. There is still some more panning that needs to be done, still not quite the 4Km touted recently.

autostoper76 · Tue Jan 29, 2019 3:10 pm

the answer to the big DISH for LHG 60 GHz

we decided not make larger dish for LHG 60. Because it brings high investment and we don't expect to much profit.
The gain could be theoretical aprox. 4 dB higher, but practical will be only 2 - 2,5 dB because of inaccuracy.
Second reason is: we are not able to got CE certification for that product.

I am sorry.

Hi

Is the align mode available on the latest stable version or only on the dev/testing versions?

Is this the correct syntax?
/interface w60g align wlan60-1

Because it does not work for me.

Also to do "proper" alignment, do I have to set tx-sector to 36 and beamforming off or is it done anyway by itself with the align mode?

Please forgive my ignorance but is there an official documentation describing the correct procedure properly or we just have to rely on each other's experiences and findings.

Thanks
