[Elecraft] {OT} - Variation on use of a coaxial switch

[Nr4c]

Note that many antenna switches short the in-used antenna to ground so you would be shorting the output of the in-selected radio to ground.  NOT a good idea. 

MFJ makes a switch that connects 2 radios to 3 antennas. Flip the switch and the antennas are switched to the other radio. Put a dummy load on unused antenna and you are set. I'm not sure of the model number but it's in their catalog.

The coax cable coming from this switch to the KX2 is a short piece of RG8X and the coax cable going from this switch to the KX1 is 25' of RG-174 (yes, I already computed the dB loss and I can live with).
