You evidently think a lightning rod will somehow increase the danger,
but such has been proven by long experience not to be the case. BS in
other words. The lightning rod doesn't know or care what is under it.
It prevents strikes in a 90 degree cone under it. Works equally well
for buildings, boats, and powerlines.

I think we are talking two different concepts here.

A lightning rod is designed to be "the" point of strike, should one occur
and equipped with sufficiently sized conductors to discharge the strike to
ground.
.
I am talking about making the building, boat, or whatever less favorable to
the strike.

It has to do with the positive column .... based on the static charge that
builds on the ground point.
