I had some idea Jim was looking for something more like this:

http://www.ebay.com/itm/P-B-POTTER-BRUMFIELD-RELAY-120-240VAC-COIL-4PDT-25A-1HP-240V-MAX-PM17AY-NEW-/290867330871

I have found NOS relays like that at hamfests for $10 each.  I used
one (a 24 v. DC relay as my T/R system is 24 volts) and mounted it in
an aluminum die cast box with UHF jacks to use as my antenna relay.  I
paralleled three poles for RF and used the 4th to ground the receiver
feedline on transmit.

This is a good kind of RF relay because the hardware is all
copper/brass/aluminum.
