I had it on the Motorola just hanging on the side of the cabinet and never
had any problems of desence of any kind. All I can do is change the ends
and see what happens. Might get lucky.

Jim:
I assumed that a seasoned repeater owner would know to do that as a
precaution.
But, if the repeater suffers from desense coming from RF at the 1 watt
level leaking from a small roll of coax, then the repeater has more
serious problems than can be overcome by 1 small shielded box.
This coax attenuator trick using RG-174 has been used on many a repeater
using a Motorola 400 Mw drive amp (UHF or VHF) and works just fine.

Except that RG-174 is NOT 100% shielded, and he is using a duplexer. If
it was mounted in a metal box, and the box was grounded to the exciter
chassis, it *might* work without causing desense...maybe.
