Shield kits for Ubiquiti?

OK, need opinions.

Who makes the best, most reliable shield kit for the Ubiquiti sector antennas. There are a few manufacturers now. Need feedback before I order 8 kits.

These are on separate towers. GPS not an issued just yet.

Thanks.

Buy AMERICAN. That's the answer. It's darn near the same thing in all cases. So spend a dollar or two extra and support someone in this country.!!!

Be careful with your wind loading.

I buy exclusively from RFarmor, they work wonders.

+1 for RF Armor.

while everyone seems to be happy with their rfarmor shields, i'd almost go with something else just in spite of his constant advertising on the ubnt forums. dude is seriously annoying.

I wish ubnt would get their shit together so you don't need these shields.

Your metric for "advertising" must be pretty low. He usually mentions it when it is a solution to a users problem.

FYI wirelessdog, rf armor is just for people who cannot plan their deployments properly.

Ubiquiti's 2.4ghz and 5.8ghz gear is rock solid they may not have figured out GPS sync yet but im sure that someone will and open it (Probably a college or university) and ubiquiti will integrate it in their products if they are not stupid.

I have tested it and it is not worth it for us as it seems to add too much multipath reflection. It makes maintaining the 64QAM rates very difficult to maintain as you need a higher SNR. 16QAM modulations don't seem impacted tho (tested with both the rocket dish version and the nanobridge version).

If the RF armor had a RF absorbing foam inside it like the andrew point to point parabolic's. It would eliminate the multipath reflection and would be good enough for me to consider wide scale deployments.

edit: Ubiquit does not like signal's stronger than -45dbm, I don't know the technical reason behind why it handles signal overload so poorly but if its stronger than -45dbm it will have a line in airview right across -70 to -75dbm when it transmit's that significantly impacts the receive sensitivity. (Regardless of what channel the other equipment is on).

edit: I don't have the diagrams on what magic is occurring inside the atheros chip SOC but it might be that the down converter is leaking too much signal into the IF when you have too strong of a signal.

UBNT gear doesn't handle signal overload for same reason as other manufactures' gear. Nothing surprising.

So the shields that someone took upon themselves to build for themselves and then the community are because no one in the industry knows how to build and deploy their network? Pfft and LOL

The same shields that he built, are being built by others now, AND UBNT integrated in to their products. Yeah, I think no body knows what they are doing. It started with UBNT in their design, not everyone elses.

You must not have been using this gear very long or something. Most of us know why the shields are important, and work rock solid afterwards.

I would say from what I have seen at least a good 80%+ of wisp's (probably higher) sure don't have a clue in the slightest how to deploy or design a network properly or even how the most basics behind how the protocol's they are using works.

They think because they put a few 802.11 ap's up in a building before that they are RF masters.

Then they hang 10 square feet worth of gear on a tower rated for 4 square feet of wind loading and run the network unencrypted with all the gear crammed in the smallest space at the top of the tower.

edit: I have not tested the RF armor sector sheild's as I do not wish to put big sails on my tower they may not add multipath reflection. But they are of no use to me anyways since I plan my deployment's.

I would partially agree with you. But keep in mind a lot of us have been doing this long before UBNT came out with the M series. Of course there are a lot more WISP's, (and I say that term very lightly, since most are not) doing it afterwards, that don't know a thing also.

This is hands down one of the most ignorant blanket statements I have ever read on these forums..... And that says something!

You are fortunate that your competition will work with you on mitigating the interference they are causing you.

Sometimes the truth hurts.

Somebody explain to me how this cluster works with all the radios in the same band and each non-overlapping frequency is used twice.

NO Shields required LOL

The little pointy thingy on the top, that's how Oh, and a proper RF set. But hey, it costs more, and we can't have that in this day and age. Well, except the companies that plan to stay around longer than the competitor who doesn't have the pointy thing on top LOL

(GPS receiver/polling, just in case you didn't get the sarcasm)

we actually roll our own! We bought a sheetmetal roller and buy the metal locally. We use enough of them that it makes it cost effective to make our own stuff, plus we have a strong background in manufacturing.
