[TriLUG] OT: comms inside a corrugated metal building

[Pete Soper via TriLUG]

Oops. I read 150 feet, not 150 yards. Sorry.

And arranging decent earth grounding, using shielded cable and making 
sure the shields are tied to the ground rods  is super important, and 
that's apart from surge suppression. The potentials induced in cables by 
thunderstorms are astonishing. And of course fiber eliminates this whole 
can of worms.
