Years ago ( when I was a young SWL )
my radio antenna was protected with a "lightning arrester".

As I remember it, it was a glass "brick" with three terminals;
ANT; GND; and RCVR
It was filled with neon, so it'd glow with electrical discharge.

I'd like to add lightning protection to my new antenna,
but I'm having a heckova time finding "lightning arresters".

At best, I see listings for "surge protectors".......
and, as I understand it, these are a one-time protection,
which counts on burning out a "mov-diode" for the first strike.
( as for subsequent strikes ???? )

Any sources ?
