In 1966, I lost a tower to a lightning strike. The tower was a 50ft
Rohn 25 with three sets of two guys. The tower was grounded an the base
with ground rods and heavy guage wire going up about 3-4 ft where it
attached to the tower legs. Unfortunately, the strike went down one of
the guys, over or through the heavy-duty egg insulators to the guy
anchor where it cracked the cement open. The tower, having lost the
anchor point for one set of guys, just tipped over into my neighbors yard. I didn't have any grounds on the guy anchor points. I had thought there was no need, since the guys were broken at several points with egg insulators. I was wrong. Lightning is too unpredictable to follow rules. 73, Bill N6WS _______________________________________________ See: http://www.mscomputer.com for "Self Supporting Towers", "Wireless Weather Stations", and lot's more.
