Sample Installations - Sticky Please

Sat Sep 26, 2009 6:07 pm

Everybody,

Please upload pictures of your installations. It'll help guys who aren't as experienced as some of us a good idea of how to do things right.

I'll get the ball rolling with an RB411, an R52 and a 24dBi grid antenna with 3m LMR400 cable.

Photo taken halfway through installation :)

Here's one of an RB600 and a RB433AH in the same box.
RB433AH bolts to the backplate with brass bolts.
RB600 used plastic stick on mounts. Hence ground cable.

Hi All
We are busy to install a mikrotik network in RSA, we have learned the hard way about winds on our high sites. We have used 38mm by 1.6mm steel poles then our August winds came and blew our hole structure down and we had to rebiuld it with 50mm by 10mm steel poles and straped it down with 10mm cables, the grids had to be tied at the back with cables aswell becaus the L bracked have broken off by the wind, here are pickture after the rebuld Image

Couple of piccy's to share, some might remember some pictures from a MUM presentation in singapore a couple of years back..

Image

How we have built a tower structure in a VERY windy location with only 3 holes in the ground as well (hard to access site and VERY hard ground) - Note fence around bottom keeps animals etc out and provides strentgh to overal structure..

Image

How we apply earthing to Coax cables at the bottom of one our our standard poles.
There has been a lot of talk in the past about the whole earthing issue and i suspect its something many people overlook.

Image

Site im just building showing how i like to make use of wooded poles with microwave dish's (i hate wooden poles)
Also, note use of cable clamps, not a zip tie in site...

Hi Justin,

I really like the three pole tower design, the added strength eliminates any issues with "sail" area from the panels. We have been using the lighting arrestors to earth the cables as well as provide some protection against strikes, are you using the shield penetrating earth kits as well as arrestors, or just the earth kits ?


Regards,



Andrew

Yip that structure can handle a lot of load with panels or big dish's, and can have the tops extended -see the flanges on top (or doubled) to give more height if required.
As irony would have it im visiting that site tommorow (first time in a year) because a bad wind in a storm has destroyed the solar panels?!

To be honest we dont bother with lightening arrestors anymore couple of points why;
1: If lightening really has a go the gear is toast, give up, its cheap gear replace it...
2: Its really the static buildup (misty water laiden wind etc) that we are trying to get rid off and it normally shows with better more solid connections and long lasting wireless cards..

The effect has been though since being a lot more pro-active in earth things (and no we arnt perfect not every site is done - just the worst ones) i cant remember the last card we have had to replace thats had a fried rx or tx in it? (for no apprant reason)

Dont get me wrong either, we have a lot of sites in harsh places like the Marlbrough sounds and had a network down the west coast (south island) so these things get some discharge around them..

So to answer the question, earth kits only.
(usualy cabinent has an earth bar in it as well for radios/other gear as well)

I'm worried about the weld penetration on this bracket.

Did you get this bracket x-rayed before mounting it?
Did the fabricator use plug welds from the back for added strength?

Hi,


believe me, this support is very safe. It's 1 cm depht. It's welded and has 3 layers of protective coating. I'll send you more pictures when I have time.

What kind of luck have you had with the DLI reboots? We've got 30 of them deployed, all running the latest firmware.

About 1/4 of them work, and are being replaced with products from Synaccess as budget allows.

*edit*
to add, all of our installations with failed DLI's are in climate controlled and power conditioned racks

Here's one I did a few years back, we changed out 8m LMR spooled on the mast for some 4metre ones the next day. Identical setup at the far end. RB600 with 2xR52 running NStreme2 over 40Mhz channels with 80mbit full duplex, it was only just over 1 kilometer so TX power is as low as we could set it!

It could probably go faster, but seemed to be CPU limited as they were pegged at 100% during testing.

We install RB very close to the antenna.
UPS for 230 sometimes crash, then we use the AD-55 or AD-155 - http://tandem.ck.ua/ups_mt-eng.php.
Monitoring food http://tandem.ck.ua/ups_mtm-eng.php.
UPS-MT-monitor can also control the power, if RB411 (433) does not want to respond (hangs).

Interesting. Glad they're working for you. We had nothing but problems, and their customer service was not helpful to us at all.

I would be more worried about the grade 5 bolts used on there then the welds. I mean the welds do not look very good to me either, and they should of built them up more. But the welder was thinking what I was, Its a small tower anyways. Good to see they sealed the top to stop water from going behind the bracket and freezing, well.. I think that was in NewZeland? probably doesnt freeze there anyways :-)

I think you should replace the bolts, the sheer strength on the grade 5 bolts is pretty low, and even witht he vibration from the lines, they will probably wear and break sooner then you expect. Just hope you catch it... Literally.... before it falls.

I was thinking of setting up a 10 meter tower in my back yard, do you think the neighbors would mind? :-)

Ok, this has to be one of two things:

1. A microwave "corner turner" (get it, grid points 90 degrees to the panel).
2. A cheapo ISP that wont buy weatherproof enclosures. Its one way to get rid of those antiquated Tranzeos. MikroTik baby!

You plug those two r52n each one on a piece that looks like a 90 degree splitter. Is that true or that is not only a splitter, but a cavity filter?? Can I use a single polarity antenna with both r52n radio chains using a 5ghz splitter??

Thank you in advance.

Dbii boards are very sensitive to earthing issues.

This is the F20 2.4GHz unit.

Here you can see the Dbii board is earthed to the RB411, which is in turn earthed to the radio antenna.
The radio antenna is then earthed to a copper water pipe via an earth strap.

Dbii boards are very sensitive to earthing issues.

This is the F20 2.4GHz unit.

Here you can see the Dbii board is earthed to the RB411, which is in turn earthed to the radio antenna.
The radio antenna is then earthed to a copper water pipe via an earth strap.

Eben, I just wanted to clarify. Do you mean the the F20 gives issues when grounded? Or that it requires more grounding?

No! The F20 does not give issues when grounded.

However, they do need to be grounded, which is why when you guys ship them, there's an earth cable as part of the package. I've not used one that's not been grounded properly, but I suspect that performance will decrease if it's not grounded properly.

Good to hear.

Was having a discussion with my boss as to what you actually meant. He thought you meant that something was going on when you grounded it.

Thanks for clearing that up.

I've been looking for something similar for a long time... where do you get the enclosure and attachment which affixes to the grids mounting arm?

To make sure I'm seeing correctly, thats a 24dbi 2.4 correct... (was thinking it's a 19)

would TRULY appreciate it, as Im getting tired of using bulky enclosures and having to field crimp lmr to fit the install. :D


Regards

Gewiss enclosures can be purchased in most countries.
Here's a UK company that sells the product.

As for the mounting to the antenna. That's something that I designed and I get laser cut. I'm sure if you take a piece of metal and play, you'll come up with something that you can get made.

It's a 24 on a nice 50mm galv pole with 3mm wall thickness.
