[TowerTalk] CDwelding a tower leg

[Cqtestk4xs at aol.com]

You ever take a lightning hit?  I have several times and it was  
uh....exciting.  Towers were extensively grounded but not to a common  ground with the 
house.  Three tower legs are not an extensive ground and  will not 
dissapate a direct hit and will likely make a beeline to your shack on  the coax to 
finish the job on its way to your home grounding system through the  house.  
You are living on borrowed time with that attitude.  Extensive  grounding 
is your best friend and the insurance company's.

I fail  to see why a ground is needed at all.  Surely the lower two feet 
of  tower is firmly embedded in dirt with the concrete anchor above  
that.  If it was done that way those three tower legs should serve as  
some pretty good ground rods.  At least my version of common sense  tells 
me so.  I will have to admit that common sense has not always  been 
kind.  Sometimes it does not make sense at all and becomes just  common 
bs.  I am wondering what it might be on this topic?   Anyone venture a 
guess?
