Hi Charles; I think you were just very lucky, wait a month or two and then
check the coax, you may have to throw it all out and replace with new coax.
I know I would not be happy with that coax.  At this end the tower is
earthed as is everything else.  So far touch wood its been OK, hate those
lightning storms we get in this part of the country during our summer, its
like the 4th of July.
