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,
heavier relays.
My experiment is written up in NCJ for May-June 2014

I was thinking of using one of these "AS IS" and if not strong enough
to use them to control the actual heavier relays.

Did you get any responses to this? I am interested. I have a number of
antennas to switch and would like to get rid of the wires.

Having noticed a new change of tack by manufacturers to IP based
antenna
selection and a plethora of IP/ Relay driven devices reasonably
priced on
Ebay -
Has anyone had any success using these items (EBAY) to control the
likes
of Six Packs or switched bandpass filters - and integrating with
N1MM or
the like ?

Please note I no longer use the WIA email address where possible
owing to
it blocking emails from sites such as VK Logger and ARRL.
