Hi again folks, I've been off the usa-tesla list since I finished my last 
coil back in summer '95, and it seems dead now, so I've joined this one. 
:-)

My question for today is:

I have a medium size coil that I wish to take around with me for 
demonstrations.  By medium-sized I mean it is a 4.5" dia by 24" coil 
firing off 2 foot sparks with input from a 12kV/60mA neon.  Outdoors, I 
have just been running a short piece braid from the coil to a 4 foot 
piece of copper tubing I hammer into the ground, but I really don't know 
anything about RF earth grounding or about what I am doing.  I'm an EE, 
and I know the all basics, but when it comes to specifics I am an Audio 
and DSP guy; much more of a mathematician and programmer than power 
engineer.

What I need is a solution for grounding indoors, especially one that will 
prevent damage to equipment that may be on the same power line, spoken 
from experience.  Are powerline filtering chokes a big help?
