What would be wrong with relays? Put em all where the antennas enter the
house, and then youd have only one control cable, and one coax, no matter
how many antennas youve got.

NTSC video extends from DC to 4.5-Mhz. The shortwave spectrum reaches
30-Mhz. A video switcher might attenuate the higher HF range.

An 'RF' switcher should work for switching two shortwave antennas. You
were originally talking about a video (baseband) switcher, which isn't
necessarily suited for frequencies above 4.5-Mhz.

RS has a "high isolation A/B/C" switcher for just $11. Would be a
shame if this switcher attenuated significantly-- and it would be nice
to have one more odd RS item that can take the place of a speciality
item costing much more.

Right now, I'm just feeding random wires so such a switcher would be
fine for me otherwise.

Thanks.
