Default Lightning Arrestor & Protection Of Receiver ?

Hello:

Very interesting comments on my question of a few days ago re lightning
arrestors.
Thank you all for trying to educate me on this subject; really find it
confusing.
Thread is a bit buried by now, so thought I'd start another one.

I fully understand that the best approach is to (also) just disconnect
everything.

But if not around, here's what I don't understand and concerns me.

Assuming a "nearby" strike, and a subsequent emp pulse that's picked up by a
receive only antenna
wire strung outside:

No matter how quickly an arrestor's gas tube fires, and diverts the pulse to
a good RF ground, the fact that it takes
a few hundred volt threshold to fire makes "any" gas tube type of arrestor
almost worthless re the protection of a receiver whose front end certainly
won't take a few hundred volts, even for u-seconds, probably.

Do you agree with this statement, or am I missing something ?

Thanks,
Bob
