I think you may need a different arm on the reflector for 450?

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.
