Default Tesla Coils was Why do we short coil turns ?

These two concepts seem to be contradictory. Some simple 1/4WL Tesla
coils are obviously close to 90 degrees long and limited by the speed
of light. The traveling waves cannot travel faster than the axial
propagation factor, whatever that value might be. For those simple
Tesla coils, there is an electrical ~1/4WL between the feedpoint and
the spark. Simultaneity is impossible in the real world.

dedicated to learning how to be a square dance caller.)

Long, long ago, I possessed a few copies of some of Teslas' original
notes, thoughts, sayings, etc. condensed in a thin little book. I can
remember reading it and contemplating what he was thinking/saying. I
got a distinct feeling Tesla seen his "magnifying transmitters" and the
"receivers" as, on resonance, being connected together by an "invisible
wire" ... I still think I may have missed a lot of what he
knew/discerned/guessed/thought/etc. He was nothing short of utterly
amazing ... possibly "insane like a fox."

BTW. I Square Danced from the time I was ~17 to 26, some of the best
times I ever had. Got into exhibition dancing in front of large groups,
just for fun ... times were a lot simpler/better then ...
