Re: [TCML] Grounding a Tesla Coil (Yes, Again)

Alright,
I'm hearing a lot about counterpoise whenever this comes up. I don't
have a lot of room to work with here, I'm only 15 working out of my
bedroom window sill. IIRC, there was a webpage on someone experimenting
with counterpoise on their concrete garage floor, and he reported corona
or plasma or something of the sort radiating from the plate to the
floor.
I'd be interested to find out more details. That would be pretty
unusual, unless, perhaps the mesh wasn't hooked up to anything.
If I were to roll out a bail of chicken wire in my front yard,
wouldn't that set my lawn on fire?
No
This is why I opted to burrying copper pipe(s) in the yard to make up
for a lack of horizontal space.
Oh, one more thing, does the physical position of the coil have to be on
top of the counterpoise, or can I set it aside and run a wire?
Yes.. put the coil in the middle of the counterpoise. That way, the RF
currents flow in the counter poise, rather than down a wire, to the
counterpoise, into the earth, and then back to the top load.
I don't
know if that's just to show the similarities of a plate in a capacitor
or for whatever reason...
The counterpoise (or the floor/earth) forms one plate of a capacitor
with the other plate being the secondary topload of the coil.
Thank You,
Brandon
Are you operating your coil outside? or indoors? If you're indoors,
running a long wire to the outside doesn't really help anything, and
could make things worse.
How big is the coil?
