Nearby Lightning Protection Quest. ?
Hi,
Have an attic located, receiving only, random length antenna.
Thinking of stringing one outdoors, but have a few questions, and concerns,
regarding nearby lightning.
a. would you folks agree that having it indoors under the house roof,
probably provides 0.0 % added protection relative to if it was outdoors ?
That any additional indoor protection due to being indoors is probably more
psychological than anything else ?
b. We gets lots of lighning strikes around here. Happy to say that they
have all been "nearby".
This is the crux of what concerns me.
I can't help but feel that if there ever was a truly direct strike on the
wire running (horizontally) outdoors,
a gas discharge tube protector like the Alpha-Delta ones wouldn't really
help much.
But, for the nearby strikes, where possibly just a few hundred volts perhaps
is induced into the wire (but enough to fry the radios front end), would the
Alpha Delta types even trigger ?
c. what's the best protection for "nearby" strikes, other than a total
disconnect ?
BTW: would grounding of the wire be equally effective as a total disconnect
of it ?
Thanks,
Bob
