[TenTec] Rig switching

[JACrux]

For years now I have used a pair of ancient Heathkit 4-way coax switches 
back-to-back. I did retro-fit them with C connectors but I need not have 
bothered - the isolation between outlets is not all that good. It works well 
with my K2 and Omni-V/Hercules 2/263 ATU combo and 2 antennas plus a dummy 
load. And I have spare outlets for another rig/antenna. The only coax switch 
I have here with good isolation (unused outlets grounded) is a "CX201" - 
maker unknown. 
The Ameritron remote coax switches can be configured to ground unused outlets, 
but are more expensive. How many kW and much isolation do you need ?? If you 
can find a ceramic or even phenolic rotary switch which shorts inactive 
contacts, you may be able to roll your own. The bump in the SWR is not likely 
to be enough to worry about.
