I think that if there was good evidence that lightening rods DIDN'T
work, we would have heard about the controversy by now. If tall
building are all equipped with lightening rods, that's good enough
evidence for me to believe they do work.

Obviously, you want to ensure that you have a pretty massive cable to
transfer all of that current around the house and into the ground.
But, I'd rather fry a $300 cable than have lightening set my house on
fire.

I'd put one in if it wuz my house.

Cable?? The rods I've seen all use 1" x 1/4" (or roundabouts) solid
copper bar.


That sure must be an expensive and very labor intensive installation.
Here in the USA I've never seen such a thing. All the ones I've seen
use cable, it's accepted practice and it works.

Seems to be the standard here (and the whole thing of lightning rods has a
complete set of standards all to itself).

OTOH, apart from pikeys nicking the copper, it doesn;t need re-doing very
often (ever??).

Before Fred Dibnah took to knocking down loads of victorian chimneys, one of
his more called upon jobs was installing lightning rods on them.
