Grounded or ungrounded, it makes no difference for the "attraction".

Nice logical theorem snipped out, love the plastic wrap idea. My 
neighbor uses a jug of saltwater filled with pennies for an equipment 
ground, and sticks his cables in a foil wrapped jar. He says it works 
because his 40 foot tower in the middle of the 90 foot tall trees 
has NEVER been hit.

That indeed is a problem.

In my case, I don't worry much because both of my very tall towers 
up on this ridge in the open pastures ARE grounded quite well 
(through a small spark gap at each leg end). When I pull the feedline 
and control connections OUTSIDE the house, I just add additional 
assurance lightning is LESS likely to follow the cables into the 
house, or lightning that hits the power lines is less likely to go 
through the house to the massive tower ground.
