Re: RF ground - what if you can't use a ground rod?

"Interestingly, TCs DO radiate fairly well at VHF frequencies, but
I think that's mostly accidental, and there's not much power there, so
radiative "losses" are neglible in any case."

	That radiation is more likely from the leads from the spark gap to the
primary than from the coil itself.  I have a small coil here which puts
out about 30" streamers.  Runs at just over 300 kHz.  When it's running
a radio in the house 50 feet away doesn't get much interference at all
on local stations, but there are plenty of "jaggles" on the TV.
