Ditto looks like an ethernet compression fitting you grafted on the unit?

Hard to tell from the small pic..

its the but end of Nanobridge: indeed just drilled it and screwed in the gland

sorry but my iphone5 comes in any day: pic taken with a 40 dollar replacement phone (lost the 3gs)

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.

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.

funny you mention because my first unit I installed with nothing but a bit of putty

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.

Ive always used the grommet, the only thing I do weird is I never clip the feedhorns in, always installed up side down if you will.

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".

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

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.

Only time we have had to take them apart is to swap a 2.4 to a 5.8 in a pinch.

I also install the feedhorns upside down. Makes things a hell of a lot easier for just in case situations.

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.

I do the same as Gunther. Just leave a gaping open hole, and secure the CAT5 nice and close to the mast with some cable ties. No water damage in 6 units since they were installed a couple years ago.

I know what thewisperer did he used outdoor RJ45 feed thru on the NB horn.

*cough*lightning*choke

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.

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.

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

Some of the older stuff I dont mind replacing! I can finally get that 2024 MTU Ive been after!

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.

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.

That's a big jumbo MTU, Do you see any sort of performance improvement with it ?

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.

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

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.

Uh, no. Copper, dude!

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

Is that just a feedthrough gland or is it a RJ45 jack with a short pigtail?

just a feed through gland: I remember when Dan from Xagyl used to package his units with a jack and short pigtail. Had problems: so did I. Don't use them any more.

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

thewisperer did you have to drill the hole bigger to make the feed thru fit or not?
