Hello Tom, Not to worry about station grounding.  A thorough plans was
worked up by several electrical engineers.  Nothing can guarantee that the
towers won't be hit, but as much as can reasonably done, has been done.

Alan,
I hope his safety grounding system is as elaborate as the antennas. they do

Sounds like entirely too much fun.
