Matt;

Sounds like your ground may be sufficient. You can test it by measuring the
resistance between the RF ground and the house ground. Ideally, I believe
you want to read no more than 1 ohm. Mine tests out a 1.5 ohms but seems to
be performing adequately. I'm also running a 4 Ga. cable from the base of
my secondary to the RF ground; even if the resistance between house and RF
ground is low, too small a gauge cable may not handle the current and it's
performance may suffer. If the resistance is too high you may have to add
additional ground rods. I use six x 10 feet x 1/2" copper water pipe.

Regards,

Daniel

Just for clarification sake, I'm curious if there's any major difference
between
the RF ground that you're all using and mine.

My ground is simply a long copper tube driven a good 6-8" in very moist
soil.  My
protection filter and my secondary are grounded to seperate tubes, and then
a
discharge rod (long wooden stick with a nail in the end of it wired to
ground) is
grounded to a third (Discharge rod used for discharging coil after
operation and
also for measurement purposes (never manually held near coil while in
operation)).

Is this an appropriate RF ground, or should I be doing something else?

Thanks,
