Hold the phone guys!
I once made a secondary coil on a classical two coiler that sucessfully
developed
an output streamer (repeatable) to a grounded target which measured 15
times
the coil length. I apparently employed AMAZING FEATS OF SUPERBLY
SUPERIOR ENGINEERING, no less! It's ABSOLUTELY TRUE!
Sorry though, I can't discuss it in any detail because I know a guy who
personally
knows, and in fact is actually dealing with, at this very minute, a
lawyer.
But, I DO STAND BY THIS CLAIM!!!!!!!!!
