If you use a good RF ground for the Tesla coil, unconnected to anything else
in your house and also use good RF line filters for all the AC supply, also
with a separate ground, you won't have much of an interference problem.  I
run my system at up to 9kva and have only a small amount of snow on the TV.
 It does raise hell with the portable telephone however.
