Dang...and I've been thinking all these years the work we do at all these commercial transmitter sites has been doing some good....

Guess I need to look for other work....

If the ground from my antennas comes into the house, I don't want that ground to bring lightning surges into my home.  At the first hint of a thunder storm, I have a single plug I remove that removes all external AC from my station.  I also have a plate at the window where all my antennas enter the house.  I disconnect all my connections to that plate for storm protection.  The only protection that really works for lightning is complete disconnection from the outside world, including grounds. Remember if your ground just has .01 ohm and you get a 100,000 volt lightning strike, you still get a 1000 volt difference across the ground wire.  So it is futile to think you can ground something struck by lightning and keep the voltage low.
