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.

I am primarily using the KPP 120 degree sector and i am not happy with
performance. 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.

If your going for Nlos I would try and stay away from 120. Even
Ubnt will tell you they don't like 120

Yeah, looking at the pattern in the spec sheet for the Cambium
antenna, it looks to be about -10db at 120.

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 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.

Sean,
Really? I was told the 90 degree cambium sector was
actually a 65 degree sector so you using it at 120
degrees? I would assume there is at least a 6db
difference between the center of the beamwidth and the
outer edges at 120 degrees.

I've only used the cambium one...works great.
You can actually use it as a 120* sector if you need
to, you just loose 3db more than at the 90* point.

Has anyone used all three of these antenna
choices for PMP450/3.65ghz ?
- KP 120 degree 3.65ghz slant sector
- Cambium Stock 90 degree 3.65ghz slant sector
- Alpha Wireless 120 degree 3.65ghz slant sector
And what was your thoughts on all of them? Did
any perform worse or better than the other?
