[TowerTalk] Tower grounding advice

[Tom Cox]

Bill,

Not unless the lightning hits the concrete directly, in which case, all 
bets are off  A direct strike can be like getting hit by an artillery 
shell. .

The theory that lightning currents conducted through concrete will the 
moisture to steam, causing an explosion, is unfounded. Concrete can make 
a very important contribution to lightning grounding. Look up "Ufer 
grounding" for the details. Interesting background.
