Have you considered adding back to back RF Armor shields.  I might try that 
today on an RD-34.

It is outside at my NOC.  We have a 10' x 10' structure on the roof with back 
to back Nanostations broadcasting 10' apart

The foil table is cheap and easy to try. If it doesn't work, you can always 
peel it off. As for the 6db result from earlier, were you outdoors in inside 
when you tried that test?

I used to use galvanizing spray paint to repair stingers that had lost their 
gold stickers, and it worked great for that.  I would clean the residue off, 
mask and spray the circle, and then paint the whole thing white.

Galvanizing spray paint may not have a good faraday effect due to the small 
zinc particle size and the lack of electrical connection between particles.  
Just a guess.  I would think foil tape would tell you for certain.

But the paint may have been just as good.  Never really tested it for that.  I 
know that eventually the vehicle somehow weathers or evaporates away and allows 
the zinc to do the proper electrochemistry when applied to steel.

I have masked the front and painted the backs with galvanizing spray paint, but 
the difference was not really very noticeable.  I debated trying foil tape, but 
just gave up frequency reuse on that old UBNT gear.

I would have cost them just a penny or two to have coated the inside of the 
enclosure with aluminum deposition or nickel paint (or arc spray zinc) to have 
eliminated much of that.

I wonder what the difference would be to put foil on everything but the area in 
the front where the antenna is...

....so it dropped from hearing at a -30 to a -36.  Still too hot for them to 
both be on-channel obviously, since they put out so much noise out the back.  
Obviously a directional antenna like a Powerbeam will be different.

In my experience testing RF armor on a two Nanostations facing opposite 
directions, ten feet apart from each other, each rf armor lowered the noise 
level by 3db.  So both of them lowered the level that they could hear each 
other by 6db.

How effective is RF Armor in reducing interference being received by an SM?  
Obviously it depends on which direction it's coming from .
