For switching the (hopefully soon to be set up) K9AY loop for our clubstation, a clubmember designed a circuit with a 4-position switch, an AC Power-supply plus some diodes etc. The AC is fed into the coax and switches the relais in the control-box under the loop. 4 positions are possible using AC and diodes.
