What was the purpose of snipping my reply and then acting as if the
ARC-5 suggestion was your own?
Here is the part you snipped:
A neon will also bleed off lightning charge buildup from a nearby strike
or cloud to cloud discharges. With a Beverage antenna its not even
local, Ive been bit by a strike several miles away.
ARC-5 receivers had a NE2 or similar which was effective against the
fairly low power of the matching TX.
