[Elecraft] Looking for a way to switch an antenna input to the KAT500

[Jack Brindle]

TopTen has a nice A/B switch with pretty good isolation characteristics. See: https://toptendevices.com/products/ab-station-selector/ <https://toptendevices.com/products/ab-station-selector/>
It requires a 12V signal for switching, I believe.

Array Solutions also sells some devices that may be of interest.

So I'm looking for a antenna switch that can change inputs in some way based on an electronic signal.  The signal can be via serial device, or network doesn't matter.  Anyone know of such a programmable switch?
