G'day,
Thinking on this, how about:
Remote antenna switch.
1. Activated by a dc signal applied via the main co-ax.
2. Drops to an internal load.
3. Sniffs the rf in a "tune" cycle to determine the frequency.
4. Selects via latching relay the designated output port (co-ax socket)
5. Switches "through".
6. Goes to sleep until activated again.
Could be powered by a remote battery, possibly charged via a very small
photo panel.
Just a thought, needs some polish.
Regards,
