Ummm, hmm. I think you have a DC short in one of the connectors meaing
a piece of braid is touching the center conductor. Test the
interconnect cables with a ohm meter for the short.
If this is a duplexer harness then the electrical 1/4 wave piece of
coax that is the interconnect cable becomes a shorted coaxial stub
which would give good VSWR but basicly absorb the RF power at the 1/4
wave frequency.
This concept is used in the heliax duplexer. except in the case of a
shorted interconnect cable you give the RF no place to go so it gets
transformed into heat by the cableing its self.
I may be wrong as well, this is my best guess. The RF world is filled
with all kinds of pit-falls and gotchyas. Just the other day we had a
piece of RG-6 as a jumper be the perfect length to attenuate CATV
channel 36's color carrier but all the other channels looked fine.
