Just to follow up and "close the loop" on this thread, I got a
Sinclair MR256 mobile duplexer, threw together a quick test setup and
tested it on my drive to work this morning... it's kicking butt
compared to what it used to do using two separate antennas. I'm now
getting good audio from five mile

Usually putting the TX up high is "backwa
Nothing fancy... single-shielded RG-58U. That's an interesting
thought that hadn't occurred to me. And with my vertical-separation
setup with the TX antenna up high, that could certainly be a factor.

Thanks for your input, I was hoping to hear from someone who had
experience with this kind of rig. I've been trying the vertical
antenna separation tactic, which *in theory* puts the antennas in each
others' nulls, but I think the reality is that there's enough pattern

I would think you'd be best served by getting the duplexer ASAP. If
your intent is to have a smaller, portable, quick to set up
repeater... the duplexer allows you to eliminate one antenna &
feedline, sets up more quickly, and works immediately without antenna
jockeying, tuning, etc. (assuming you
