Inspect the cables or at lease switch one or both out at one end and see
if a prevalent change is made.
Could be a feed horn but unlikely I would shoot for pigtails first.

Sooooo much information, so easy to find.
one question though, They have atpc set to -35 on these, does that
basically turn atpc off, or could it cause a problem?
Im pretty sure they have a loose antenna or damaged feedhorn/patch
cables (this was a lighnting replacement of a ptp500, reusing the
cables/feedhorn)
The system statistics showed a variation of received power ranging
from -47 to -78 with a peak of -110 , -78ish being current. Transmit
powers show a variation of -15dBm up to 21 dBm (I did not notice the
negative value at first). This would account for the range of
Received power except When the Status screenshots were taken, the
transmit power on both units was at 21 dBm with a 77/78 receive power
on each side. If the output power is accurate, the receive power on
the remote end would be at the peak, not the mean.
