We have a local school district co-located with us on a water tower and
they're complaining about noise on their input. I pretty much told them
they're SOL until we need to add or replace cables since they're all in
an 1-1/4" PVC. So we'll have to run temp cables up, rip all the cables
out of the pipe and pull new ones. The village said we have to be in
conduit. And we do have a couple cables in use that aren't shielded.
They didn't offer to pay for it, so too bad.
They're running a Kenwood repeater in an outdoor cabinet. Maybe 12U.
Obviously that's not going to fit the proper large can cavity duplexer
like a Sinclair. Plus they have >4.5MHz split, so no doubt that let them
use a smaller rack-mounted duplexer.
So I'd be curious to know what the setup is on this 149MHz repeater. Are
they using a small crappy duplexer with a large split, too?

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

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.
