That's easyjust wind up about 25-30 feet of RG-174 coax and install
that between the 2 watt exciter and the Vocom Amp. That wound up coax
will give you about a 3 Db loss at 146 mhz and supply only 1 watt to the
amp instead of the 2 watts. Very simple and highly
reliable...nothing to
In deed agree on that. Except I have to get some type N coax connectors.
That is what I did for the Motorla amp when it needed .400 ma. But I've
changed all that and now needs type N. One of these days trips to the

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.

Hi Jim,
I really don't want to argue with you, but it can

comes down to a number game (the specs) and a

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.

Eric, I stand corrected. It is not a circulator, but a DCI Band Pass

So it sounds like what I need to due is look for a duplexer for one

How about this ? depending on the size of this coiled coax assembly I would

I checked a few of the other big repeaters, and they have just as much side

down to around 10 kc either side of the transmit frequency, and not as bad
