I have several situations with UBNT as you describe working very well. As
with anything with wireless YMMV.

We get decent near-LOS out of our 3.6 450. NLOS, like 900 NLOS... not a 
chance in hell. I suppose my house would be an exception, although I'd 
still call it near-LOS. I have a very old large maple tree about 100 
feet away (in the neighbor's yard) directly in the path. Beyond that it 
is clear. My SM is on a reflector at 40 feet. And the sector is at 225 
feet. One mile away. I get about -57dBm Rx power level. Works a hell of 
a lot better than the UBNT ever did, that's for sure.

You can actually use it as a 120* sector if you need
to, you just loose 3db more than at the 90* point.

The RF-Elements 100degree (-6db) works quite good for us.

It is a bit smaller than the Cambium 90 degree sector.

All I have used is the Laird OEM antenna as well. The null-fill is nice. 
It is definitely a -6dB 90/-3dB 65. I have found that it rolls off 
sharply beyond 90.


Cambium claims >32dB F/B ratio. I know Mark @ Amplex has mentioned this
