Re: How do I protect supply wires

I was just thinking if one was worried about a strike to the cables between
a PIG and the sparkgap,  why not make a strike rail for the cables (out of
copper wire and maybe attached to the PVC pipe enclosing the cables) and
return it to RF ground at the base of the secondary.
