And this brings up an interesting system design question.. do you spend 
some limited resource (i.e. cash) on better connectors or on protecting 
against connector failure.  It's not an obvious trade: One likes to 
minimize failures, but the protection circuit also protects against 
other things: Antennas getting broken in the wind, for instance

     Reminds me of the circuit a Ham friend of mine built in the 1970's to protect his amp.  It tied into the Reflected port of his SWR bridge and used the rising VSWR to trigger an SCR that would trigger a relay to cut off the amp if his antenna's SWR rose suddenly.  I believe he got the idea from a Navy rig he worked on while in the service.  FWIW.
