   Ya know Ed, I 100% agree.

  To my way of thinking a Tesla coil secondary has a infinite SWR,
SWR is the ratio of Emax/Emin etc, In a 1/4 wave resonant
secondary we have Emin at the bottom, Emax at the top. and the
standing wave WITHIN the secondary is in theory, Einfinitely low/
Einfinitely high.
  I would think that we would be talking the resonator base driving
Z verses the output Z of the driving source.
