Joe, there is a large family of such things available from China. I had
one working to switch my RX antennas. I coupled the 315MHz RF to the
inner condfuctor of 300 feet of coax and picked off the "wireless"
signal at the other end. It switched fine, but I had trouble with other
aspects of the setup - losses in the DX coupler for the relay power -
and eventually scrapped the thing. The relays may be a bit light for
transmit antenna switching, but should certainly work to switch other,
My experiment is written up in NCJ for May-June 2014
73, Pete N4ZR
