I think it was Jim Lux that had an arms length list of references posted
about that a day so or ago on lightning prevention with dissipaters.
I don't know what this has to do with WD4K? His post does not mention them
or allude to them at all. And I don't know how my post got on the same page?
My post concerns the fact that the FAA tested them at several locations and
came to the conclusion that they did nothing other than become a fire
That's one empirical source for you.
NASA is another.
If I remember right you spent some money on some of those things and are
quite reluctant to bring yourself around to realizing that maybe you have a
product that may not give you much in return for your investment.
But if you are a believer that's ok too if it gives peace of mind.
