Stop being so... logical.

case.

Maybe it was epmp.
I will shut up now.

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

I would expect -67 to -70 under the following assumptions:
- operating in 5.7 GHz
- 19 dBm xmt power on AP
- measuring rcv signal at SM (higher at AP because SM can exceed +36
EIRP
xmt)
- straight down the middle of the sector
- downtilt properly adjusted on sector
- no multipath or rain fading
At the edge of a sector (+/- 45 degrees azimuth) expect to lose 5-6
dB.
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. What
kind of signal should I have at this range?
