Hi Terry,

On HF there are a few remote antenna switches.  The ones I know of use open 
frame relays and there is a high SWR even at 10 meters. Pushing these to 
the UHF bands would not be wise.

If you really need to switch antennas remotely, consider using coax 
relays.  You can pick them up for $20 each at hamfests but bring an ohm 
meter with you to measure the contact resistance.  You will need 3 of them 
to switch 4 antennas so for $60 plus a couple of switches, you have a 
remote antenna switch. Don't forget to waterproof them.  If you have 4 rigs 
in the shack, you'll need 3 more. If you buy new, you could probably get by 
with something like the CX1054A by Tohtsu - DEMI has tehm for $60 each.

Have fun
