Lightning Arrestors Question
Hi,
Saw a picture somewhere of an in-line lightning protector for a HF radio
receive only antenna.
Coax style.
Apparently has the typical gas tube, and when activated shorts the center
conductor to the braid.
Was wondering a bit about this.
I seem to remember in the old days, there was always a third tap on these
sort of things that you ran a solid ground to, e.g., a water pipe.
Does merely shorting to the braid provide "good" protection ?
Any thoughts would be appreciated.
Also want to ask: what about voltage surges of a few hundred volts or so
induced on an antenna lead from a nearby lightning strike perhaps
..
The levels way below what would trip a gas tube I would imagine, but still
more than enough to ruin a front end of a receiver.
How does one protect against these without breaking the bank doing so ?
Thanks,
Bob
