Longitudinal wave antenna
I was loking at Eric Dollard's video "Tesla longitudinal electricity" with Tom Brown and Peter Lindemann. The question is about the antenna construction. The wire, rather the coaxial cable, for the secondary coil is wound on 16 spokes originating from a central hub. Each spoke is notched on the top (and may be also on the bottom?), so as the wire wounding fits in these notches. The way Peter Lindemann explains it that the first turn goes on the "bottom" and the second turn on top of the first and this sequence repeats about 20 times. The way Lindeman explains it is not clear to me. Are there two turns in each notch on the top of the spokes or one turn in the top notch and the second turn below the top one in the bottom notch. This latest configuration would result in two parallel flat spiral coils seperated roughly by the thickness of each spoke. Any insight is welcome.
Also a question about the secondary coil made up of 3 - 1" wide by .010" thichk bronze strips. When I calculate the surface area, as advocated by Eric Dollard, of the primary do I calculate just the outside area of the coil or individually all three strips making up the coil? Somehow they don't ad up either way.
One more question concerning the equipment Tesla used for his Colorado Springs experiments. He had among other things a Westinghouse generator/transformer rated abut 26HP. If one would like to repeat (very carefully) some of the experiments at home on a much smaller scale, what size transformer would one need, i.e. input and output Voltage rating and Amper rating. Would a transformer rated, say between 10 to 20 amp, be sufficient at what output Voltage?
