[TowerTalk] Relays

Hello!

I wonder what kind of relays should I pick when building antenna 
switches. The coax relays are to expensive so that is not an option.

I have actually used car relays for a while and they seem to work 
quite ok. I would like to know though what ratings should I suppose 
to look after? How many amps, the width between the "connectors" 
etc. should they handle? Of course this depends on how much 
SWR and power I'm using but if I say that they should handle 
1.5kW and an SWR of 2:1, atleast!?!
