[TowerTalk] Tower lightning quiery

[Woods, Eric D (edwoods)]

I don't think that the I*T product of 6, 6.6 or 10M wire rope is small 
enough to allow a 50% probability lightning stroke to cause problems with 
their mechanical strength.

oh yeah, those ore telephone company terms for different size guy strands. 
 M=1000 lbs tensile strength.

Grounded guys scares me to death.  Remember the recent post about "four
feet of an antenna disappearing" in a lightning strike ??

Picture four feet of one of your top (grounded) guys disappearing during
the windy conditions which can accompany a thunderstorm...
