I had bad desense on a uhf msf 5000 with a cellwave
526 duplexer and aar preamp.
Whenever I added the preamp I had bad desense. Went
crazy adding filtering in the tx, rx and duplexer
tuning.
After days of playing around found I had a bad jumper
cable between the repeater and ant that was generating
noise. Replaced the cable and everything worked fine
with no pad.
