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.
Here’s an RB600 mounted in an IP65 box.
no grounding for the board?

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.
My PC boxes;)
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
Couple of piccy’s to share, some might remember some pictures from a MUM presentation in singapore a couple of years back..
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..
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.
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…
This is pretty typical of all our Smaller AP’s. We have 5.8 back hauls to a Local 900Mhz XR9 system
What we have up top
Here is a custom job I did for the top of a building in the center of town
Proof that cisco and mikrotik can live in the same box This is 224 feet up on a coal burner for a power plant. Coal dust was an issue so silicone was used on the door and vent holes.
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 ?

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)
PS- You ever get down this way Andrew? -Beer…
Hey Justin,
Yes I come down that way every now and then, I am actually down there next week. It would be great to catch up for a beer.
This is a bit ot, so might be best to email me tauranga at btg.co.nz

Hi,
this is how to install a tower PART1
Mount the tower and the steel wires. These are steel wires of 8mm of diameter.
Mount the base tower and atach the tower to it with some help.. 
Put the different level wires into the wires installed supports
Hi,
this is how to install a tower PART2
Test and revise the tower with care when wires are fully installed
Claim for some help again to go up to the tower and
easy install the equipement
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.

The hole through the wall is for 220V AC that’s supplied from UPS in server room.

Connector makes it easy to shut down power when maintenance is required.
28V / 12V industrial PSU
28V DC is run through LM7824 to reduce to 24V
2 x RB433AH
2 x R52H
2 x R5H
Bottom fan draws air through a filter
Top fans expel air into cavity behind the box
Cabinet is earthed to the antenna mounts and to an earth rod.
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.

UPS-MT-monitor can also control the power, if RB411 (433) does not want to respond (hangs).
