Before you buy anything additional try all the receivers on the one or two
split signals. T-adapters and short lengths of coax from the antennas to
the
receivers would be all you need. With the antennas up high and unless
you're
trying to receive weak signals, the split signal might still be strong
enough
for what you want to receive.

Thanks Frank. I actually have a cheapie $5 splitter from Radio Shack. I've
got a Pro-2026 and a Pro-2004, both tied to a Radio Shack antenna. Off the
splitter, the 2026 receives fine but the 2004 doesn't get anything at all.
With the antenna straight into the 2006 it picks up juts fine.
