What switch(es) have adequate isolation to switch an antenna between two
amplifiers?

Ant 2, switch the antennas between the two amps, and reset the drive level"

Thanks Jim, that is exactly the response I was hoping for.  My big amp is
now a TT Titan III. I retired a pair of 425's a few years ago.  My plan is
to have dpdt relay on the output side of the amps, and switch the ptt lead
open or thru on the Titan when it is off or in line.  Switching between the
two will be a single external switch throw, a push of ant 1/2 button on the
k3 and hitting the standby/operate switches on the amplifiers. No excuse now
not to order a KPA500.  I'm looking forward to it.  HNY  73 bob de w9ge
