Assuming you are building for spark output your main RFI problem
is going to come from the secondary base wire. The base wire is a
low voltage, high current output that will energize or "power up"
the local ground. If you ground to your 60 cycle breaker box you
are turning the neutral wire into a radiating antenna for a
tremendious amount of RFI hash. My experiments verify this
conclusion. I advocate the use of a low impedance, dedicated, RF                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                              
