[TowerTalk] Lightning protection (?) for Ameritron RCS-10 antenna switch

[Pete Smith N4ZR]

I just bought a new Ameritron RCS-10 to replace my old switch, which was 
damaged by lightning.  In reading the instructions, I was struck by the 
suggestion of making  2 6" diameter turns in each coax line coming into 
the relay box at the tower, no more than 3 feet from the switch itself, 
what they call "lightning retarding loops."

I don't think I've ever seen this anywhere else, and wonder if there's 
anything to it. It doesn't seem as if there would be enough inductance 
in such loops to offer any degree of protection.
