I guess I get to talk about this now. Some of the new A/B (minus FSK,
connector anyway) 5GHz APs were built with the internal jumpers
reversed. We put up some new sectors and noticed the beacon power was
very weak.. because it was on horizontal, not vertical! This is bad for
430 interop, and obviously just as bad for 450 pre-13.2.. weak beacon,
interference.. no worky.
So yeah, now the beacon is on both polarities. And if you have an AP
with reversed jumpers + 430 SMs, you'll have to use MIMO-A 430 interop
mode (which I believe is now the default) instead of SISO. Obviously
with MIMO you get 3dB less beacon power, and for 450 it doesn't matter,
for 430 it might depending on noise levels, etc.
Shit happens.

Noticed this in the corrected list. Does this mean that the PMP450 is
polarity agnostic now in all frequencies (specifically 5 GHz)?
PMP 450 AP 22943 CPY-9983, CPY-9631
Fixed problem when AP/SM has crossed RF cables and would not
register This problem has been resolved in System Release 13.2.

It is here!
We released 13.2 this morning officially. Come to our forum to
discuss anything about it.

*Thanks*to all of you that Beta tested this software with us, and
helped to make it stronger and better than ever. Now that this is
here, we’re hard at work on delivering the next round of enhancements
(code name 13.3 (pretty original, huh?)) which are right around the
corner.
The momentum is building on the PMP 450 platform.
Thanks again,
Matt
