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.

Hi,
Yes this looks interesting as does the ones from Dewey. It seems that top
ten devices also has a 6 antenna to 1 radio switch. Anyone know if it can
operate the other way around? 6 radios to one antenna (kat500)?

Jack,
Thanks for bringing this to my attention... it is just what I have been
looking for to switch between my main and remote operated stations!

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/>
<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.

Hi,
I use a Kat500 with my K3 and KX3. However, I have a number of other radios
which I would like to use with the Kat500. 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?
Thanks, Tom
