Hi Mark--The best thing I have done is to add some HF and VHF
multicouplers to run multiple rigs off the same antenna. The best
performing ones I've found are made by Stridsberg Engineering in
Louisiana. Visit their website at www.stridsberg.com . I use the active
4-port versions of each and get no discernable crosstalk or signal
attenuation. In other words the channel isolation is excellent on these
units.

Obviously, if you wanted to switch between antennas you could add some
switches in-line as well.

Hope this helps.

Hi...

I currently have four Sony HF radios which will shortly be joined a JRC
NRD-545. I also currently have two antennas, a longwire and a di-pole.

Time for a tidy-up! What does everybody do when they want to share two or
three antennas amongst several radios (short of constanly unplugging and
replugging everything)?

Can I simply build myself a switch box? Put each antenna onto a common bus
and use switches to assign to the various outputs that are connected to the
various receivers?

Can it be that simple? And what of using two antennas at once? Anybody
experimented with this? Any gain (no pun intended) in doing that?

I'm thinking of feeding all the record outputs to a small multi-channel
mixer. (I currently have a home recording studio, so I can then feed the
output to a nice amp and set of speakers).

Mark.
