Why not use two Dow Key type relays each SPST. They come in several DC
voltages and 115 VAC. They will handle the 1500 watts, have low SWR, all you
need is power source and a SPDT toggle switch. Dow key type relays sell for
about $30 used last I looked, kind of old school but will sure do the job.
You would probably want to parallel up another signal relay to switch ALC
and key line as well so relays look like a good solution. 73 Ron W8RJL

Subject: [TowerTalk] Transfer switch?
Does anyone know of a source for a reasonably priced manual RF transfer
switch, i.e. DPDT with either UHF or N connectors? Reasonable = < $100.
Needs to handle 1500 watts @ HF.
I want to switch 2 amplifiers (solid state & tube) between 1 radio and 1
antenna system. Yes, I can use 2 SPDT switches, and will do if a DPDT is
not readily available. Google turns up a lot of relays that seem designed
for microwave use and broadcast quality items with one too many zeros in
the price.
