I think someone mentioned quite a while ago that they used a simple radio shack A/B or A/B/C pushbutton switch designed for vcr/cable to switch their receive antennas. I skimmed through the archives

I have used this type of switch for years with varying success. The older style (square pushbuttons) of A/B or A/B/C switch has a more positive "feel" when the switch engages. The newet style is a bi

The ones I have taken apart are just simple mechanical switches and as such should work fine down to DC. Isolation at VHF and UHF is typically a minimum of 75dB. At 1.8 MHz its probably in excess of

In fact, the Radio Shack A/B & A/B/C TV switches are quite good. What makes them especially useful is the fact that in addition to 100+ db isolation between ports, the unselected ports are automatica
