The RF-Elements 100degree (-6db) works quite good for us. It is a bit smaller than the Cambium 90 degree sector.

I am using the Cambium 90 degree sector in one application and its NLOS and works very well. Just wondering if anyone else is having similar results to that.

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 before, short range SMs (like 1/2 mile or so) seem to get crappy downlink SNR. They are apparently hearing the opposite sector on the same frequency which points to the F/B ratio. I have seen this as well. I actually put up a post on the Cambium community about it last night.

I would assume there is at least a 6db difference between the center of the beamwidth and the outer edges at 120 degrees.

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

Did any perform worse or better than the other?
