Subject: Re: [TowerTalk] Castastrophic Consequences of Connector Failure?
<snip>
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.
