This Arduino 8X1 is superb at controlling a DXE 5 KW box mounted at the 
base of the tower with CAT 5 cable 150 feet long.  The Arduino is in the 
shack driven by the AUX output of the Ameritron RCS-12 which provides 
either automatic  BCD selection from the Icom or manual selection by the 
RCS-12 push buttons.  If you don't use the RCS-12 a small rotary switch 
with a wall wart will work.  You can't beat the price.

 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 ?
