Re: [TowerTalk] Conductive Concrete and Grounding

They were not experts that you heard that from.

It is true that there is nothing you can do to prevent a strike but 
there is plenty you can do to deal with one and prevent it from doing 
damage.

Lightning is not unpredictable as many think, as to how it will travel 
to ground or what path it will take.
The only thing that is unpredictable about it is how large of a strike 
you will get.
