Hi Wil,
Interesting circuit - and awesome streamers! This is potentially a
KILLER coil if it arcs to you, with the secondary floating at 5 kVDC.
From an RF perspective, the system is already grounded through one of
the primary taps (the 5 kV input on the tap 2nd from the bottom) and
then back through the two power supply filter capacitors (8 uF and 4700
pF) to ground.
Adding a counterpoise connected to ground may improve performance with
this system, but will also increase your odds of electrocution. There
are old Tesla coilers, and there are bold Tesla Coilers. But there are
no old, bold, Tesla coilers...

Dear Group,
I built a HF VTTC based on this circuit:
http://4hv.org/e107_plugins/forum/forum_viewtopic.php?126638.0
I added a charging reactor in between the hv out from the doubler and the
resonator. It smooths the output and reduces the noise considerably. I
was wondering is there is a way to ground the low voltage side of the coil?
I was hoping grounding the coil would improve performance and reduce EMI.
I am tempted to use a vacuum capacitor between the bottom of the coil and
rf ground. Will this work or is there another circuit that will allow me to
ground the coil I can use?
You can see my setup here: http://youtu.be/4PvLM8yMucI
Cheers!
