VSWR is not applicable to TC's or magnifiers, as they 
do not exhibit standing waves to any significant degree,
especially after a top load has been added. 
Models of Tesla Coils that treat the TC as a simple 
lumped-element resonant transformer turn out to be far 
more accurate than the antenna theory models.

The additional voltage gain is simply due to the resonant 
rise that a standard series LC circuit exhibits at resonance.
