Did you figure out the Z0 of your coil using the Tesla coil
math, and then just assume there were no standing waves, or did
you prove the absence of standing waves through experiment?

The standing waves don't have to be eliminated,
just reduced until the traveling wave dominates
the waveform. I added 600 ohm non-inductive
resistors in series until the reflections were
negligible and the traveling wave dominated the
waveform.
