I may be thinking of something different. I recall one product needing a different arm to work efficiently. Maybe it was epmp. I will shut up now.

Your assumptions are pretty well right on my system setup. Except I am about 30 degrees from center of sector on this SM. This is my link status. AP -76.0 (-79.6 V / -78.5 H) SM -80.5 (-83.0 V / -84.0 H) with 22mbps downlink test. Expected more. The cambium 90 sector antennas are new but AP's are pretty old pulls from a deployment that never panned out. Think they are back from when PMP450 line first started shipping. This site has a PMP100 2.4 cluster running out of capacity. Was hopping to overlay with 5.8 450 and just drop the SM's in existing reflectors of higher tier users that had LOS. > I just deployed 4 90 degree Cambium 450 sectors on a 300 foot tower. > I have a very clear LOS CPE at 6 miles with a reflector dish.
