[TowerTalk] Relay lightening protection

[Rex Lint]

This reminds me of an incident when I worked at Sanders in Nashua NH.  An EE
thought he'd play a joke on me:
"Here, hold the ends of this coax.  I've got to measure the resistance...
It's a little less then a mile long..." (and it was coiled on a huge reel).
I held the connector shells, one in each hand, and he put the VOM across it.
"Thanks for doing this," he said, as he pulled the VOM leads off the coax.  

This did more than "bite."  I damn near peed my pants.

He laughed.  I haven't liked EEs since.
