The question (finally) is this: was it designed to pass the energy by
RF
coupling? Isn't that a bit lossy on what is a weak signal anyway?

And have I ballsed it up by connecting it electrically? I guess it
could
have been some sort of lightning protection, but I can't see it being
all
that effective, and it's in a loft now anyway...

What make was it?. Wouldn't have been lightning protection anything like
that is akin to ****ing on a nuclear explosion let alone a house
fire;!...

So half a mil of varnish is going impede a lightning bolt that can travel
through thousands of meters of air (quite a good insulator - look at all
those 440kV grid cables).



400 kV so I'm told .
