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

[Randy Farmer]

I concur with the comments on the Top Ten 2-way switches. I'm using 
about 10 of them at various places in my SO2R contest station antenna 
and BPF switching networks. They work well and have good isolation. I'm 
also using a 6-way for RX antenna switching. It's simply one port 
switched to one of six, so it will work just fine either way. RF doesn't 
care which way it goes through relays. A nice benefit of the Top Ten 
switches is that they're internally interlocked, so it's electrically 
impossible to select more than one port-to-port configuration at a time.

73...
