[Boatanchors] Coax Switches and Wire Antennas

[Bill Stewart]

I should have mentioned that the power would be generally below 75 watts to the antenna and CW only. Tnx for the info Jim and Carl.

Bill,
Coax switches are designed for the voltage levels encountered in a matched 
50 ohm environment.
Transmit voltages on an unmatched single wire could exceed the design 
voltage and/or current levels of the switch.
