One sample is no statistic but I put up three "discharge" devices on my tower
of my own design, each a short piece of 7 wire conductor, each with the wires
spread apart on top of my tower.
I live in a high risk area (and lost my house due to a lightning strike 1998).
So far I have had not strikes, to my knowledge, in my tower and my "corona
brushes" are intact.
I can't tell if they really works or it is or if it is "snake oil and bat wing
powder". Time might tell but I hope not.

Hans - N2JFS.
