Hello:

We get a lot of lightning strikes around here, and was wondering about
this:

Presently have a receive-only random length wire running around the inside
of my attic....

But, does the roof provide any protection ...

Or, is the fact that it is indoors really meaningless ?
Thanks, Bob


The roof has absolutely no significant magnetic properties, right? SO...
the high current of the lightning is the "primary" of a transformer. The
wire in your attic is the "secondary" of a transformer. A pretty poor
transformer, but with that current, it'll induce lots'a voltage in your
wire...roof or no roof. Right?
