I had a short back bone link from one small AP to another so used a pair of NBE-5AC-19's expecting an Rx of around -55. After connecting the link the best we could get was a -66 on Chain0 and a -77 on Chain1 when the radios were at the proper tilt and azimuth. With help from the Alignment Tool we got it down to a -60/-70, but AP end of the link was aimed about 5 degree down rather then 1 degree up. We could achieve the same Chain0, Chain1 imbalance the other way with the AP aimed 1 degree up and the Station aimed 6 degrees down. I replace the Station end with a PBE-5AC-300 and dropped the Chain0/Chain1 signals to -60/-70, but no better. So, today I replace the AP end with another 300 and the signal dropped to -47/-47.
So, the question is has anyone else seen this behavior in the NanoBeam? We have a bunch of them in use on PtMP AP's using sectors and they work just as expected, but when used as PtP this weird astigmatism shows up. Phil
