Re: [TCML] 1/4 wavelength theory ??

>From the pic I can conclude that couplig of your
tesla coil is lower than coupling of my coil.
And I have lower H/D secondary ratio (12":3.5") 
But you have comparatively bigger top load.
And is that some kind of black/dark coating on your coil?
Maybe  racing sparks on your coil appear becouse
of the material used?
