If I had a VHF repeater with a high gain omni and a very low noise pre-amp, I
would hate to have any digital equipment on the same hill. But those years
have long since passed.

I don't think so. I am assuming they probably didn't install some connectors
correctly. Unless they are using some extremely crappy gear the RF portions of
all half decent repeaters are shielded very well. Unless they modified the
repeater leaving some shielding off the connectors are the most likely source.
I guess there could also be punctures or some such in the coax as well.

Has anyone checked their connectors/connections between all RF points?
Antenna to cable, cable to duplexer, duplexer TX/RX to repeater.
Most of the time I have seen Two Way equipment either be interfered with or
interfere with someone else it is a connector issue. The only other case I have
seen issues should be able to be determined by an intermod study. I doubt it
has anything to do with intermod. My bet is a faulty connector. I would assume
it is the RX side so I would check the RX Repeater port to the RX port on the
duplexer and then the rest of the connectors.
Not saying it can't be the the CAT5, just that if all is good on the
antenna system I haven't ever seen an issue and I have a lot of sites with both
two way and 900, 2.4, and 5GHz operating on all kinds of speeds both POE and
not.
