So is this right ?

First thanks for your responses.
My strongest local station is -16 dBm (from my radar plot)
If I point a 23 dBi antenna at it that gives me a +7 dBm signal at the mast, so less than 2 dB of attenuation (coax) would possibly cause damage?
Is this right?

I don't see how typical signal levels and antenna gain would be able to put a tuner at risk of damage.
That's what I thought but I didn't know about a-typical gains like 23 dBi.

Immeasurably greater than the combined strengths of all broadcast signals in your area are the RF pulses from lightening discharges.
Will the extreme gain magnify these RF pulses more than a low gain antenna?

I'm immune direct lightning strikes, I'm in the "cone of protection" of a large lighting rod/tower that a local company thoughtfully erected nearby unfortunately they strung high voltage power lines over it.
