You may be right, just everything about Tesla coils screams bad for RF devices to me =) I have very little experience in the HV department though, so on that note I officially endorce the creation of an HV forum. I know entire other forum sites are devoted exclusivly to the HV stuff, can't hurt to have a corner here to attract some of the HV brainiacs out there =) I'd like to learn more, like many people plasma globes and jacobs ladder have fascinated me since I was a kid. I've killed a meter already trying to measure the AC voltage using a sheet of tin foil to capacitive couple to the front a 25" TV. I'd like to know enough to have some fun be be safe.
