[Lowfer] Need Antenna Relay Help

[William E. Isakson]

Andy, As I recall, the TS450S has extra antenna connections.   You could
connect an e-field short antenna to it for receive only and that would
solve your receive problem.  The e-field antennae are very good for receive
and would cover any frequency you have there.  Basically it is a short whip
with an FET amplifier.
