I like the colour coordination though. Beige RJ45 pass thru (maybe grey?), which I have never seen, and matching j-arm.

too bad the gland is not big enough for pass through with rj45

I saw your pic on how you do grounding on FTP. That is how it is done in the 'big time', kinda.

John Galt posted : Application of 1 " wide 3M 1181 Electroconductive tape to the non-RF side of the plastic cases and bonded to the drain of the FTP will help immensely to dissipate the static. Proper application includes a through cleaning of the plastic surface with alcohol, the gentle warming of the tape and case then the application of the tape and sufficient pressure to affect adhesion.

It is also necessary to make a bond from the FTP to the tower at the top, the bottom, and at the cabinet/building.

While this -might- not be worth the time and effort for most CPE installs, it is imperative for APs since many customers are affected by failures at the POP.

gunther_01 posted : You got to keep in mind with these radio's that there is no path to ground except via the shield or negative on the POE power. NON... It wasn't that long ago they didn't even have a darned shielded RJ-45. We have lost them all, and in any configuration there is. It's just luck of the draw.

If there was a proper method to ground the chassis, it may help. And yeah, some can say having the mount grounded will help reduce the plastic case static build up, but I'm not buyin it. The are under $100 each. Just stock spares. That's really what it boils down to. Cheap is, as cheap does. If you want a radio that will survive it all, there are other devices for you. They are of course priced accordingly. And they fail too LOL

Not yet, too much of my network is still 1522/1524 max L2MTU. I hope one day to have it all swapped out, and finally pass a full frame packet in a VPLS tunnel end to end on my network without fragmentation.

Some parts of my network are really old.

We use it on tower sites, but that hasnt made a huge difference. Earlier this year lightning hit directly a site and blew 2 up in one crack along with the PoEs and router.

Holly crap, is the tower grounded ?.

One thing ive seen the cell phone company's doing on their sites they ground the antenna's mount's with 6AWG to a grounding bus at the top of the tower that runs down to their grounding ring. You might want to look into doing something similar.

Also don't forget the anti-ox on your grounding. I had to re-do grounding at once site because I never used it. After every storm the 3 devices near the top of the tower would crash and require a reboot.

When I tested the ground and found from one leg of our tower to the other leg's grounding rod it was 2 megohms. That was no good so I ran a new wire lower on the leg to the grounding rod and put some anti-ox on it. Now its under 300 ohms from anywhere on the second section to ground.

We also ground our enclosure box, Bypass our ups's for the POE ground as well as ground our switch's.

I have found ups's will have battery’s explode and the board inside will suffer damage if you have the poe's ground through the UPS.

Customers, not really, after the sour taste of tough cable gave us we never tried the new stuff.

I can't say I blame you, Its caused us tons of grief and re-work. The level 1 tough cable is by far the lowest quality junk wire ive ever worked with. I regret making the mistake of trusting ubiquiti to make wire.

I have since moved back to other vendors for the cable and will not be considering ubqiuiti cable until the relaunched product line has been tested for 2+ years by the community.

Its the only time I have to replace them, we lose a handful to lightning just like any other radio.

Are you using FTP/STP wire by chance ?

We use it and give our POE's a dedicated ground that bypasses the ups's ground. (Our boxes have their own grounding rod). So far we just have POE failures after pretty much every big storm. We have not yet experienced a failure or switchport failure from lightning yet.

If you guy's don't mind me asking, What issues do you encounter that require you to take the integrated radio/dipole out?

No NB failures for me so far, but I have had a few customer cancellations. I retain ownership of the antennas, so if the customer cancels, I want to be able to take it apart without cutting the wire in case the client signs back up or someone else moves into the home.

The only time ive had to remove it has been when im replacing the level1 tough cable with proper wire that doesn't lie about it being uv resistant. (I have a 100% failure rate on level1 tough cable within 6 months to a year and a half)

Even in the winter its not been that big of a deal to get it out you just need a small thin enough standard screwdriver to pry it real good.

I have never had a nanobridge fail not even once that was not caused by an incorrectly crimped wire.

I only have a few NB's, but I do the same thing. Makes it much easier to wiggle the feedhorn back out. In the cold winter temps, I can hardly imagine them surviving when trying to pry the plastic open if assembled "properly".

its still working: even that grommet is not bit enough to push through a terminated cable so it still a pita.

I am starting to use more of them and the next post will explain why.

OHSrob posted : We just throw the black plastic part in the garbage and seal it with ducting putty. It keeps the moisture out and eventually drys out.

I have over 90 deployed nanobridges and not a single failure other then user error caused by incorrectly crimped wire.

This is the toughest product ubiquiti makes far tougher then the rocket M5. I just wish it had more ram.

gunther_01 posted : We have never used the grommet that came with. It seemed to compress our outdoor cable way to much. The grommet gets pitched. And yes that means non of them have anything. No failures. If you think about it, any water that (may) get in there will settle at the bottom and drip out of the feedhorn mount.

Almost all CPE's will have the feed horn up a degree or two anyway. The only failures we have are lightning, the stupid reset to defaults, and lack of high power on bridges LOL. Of course there is the impossible feat of trying to get the damned things apart when there is an issue with a feedhorn. Might I add the lack of individual parts for replacement as well. My kids love the frisbees though, I hate the shelf space they take up, and overall waste.

The grommet is the last thing I think about to be honest.
