RE: Capacitor Help
Original poster: "Lau, Gary" <Gary.Lau@xxxxxx>
Connecting the RF ground (your chickenwire cage) to mains ground was
suggested as a safety measure, in case something bad happened and your
RF ground somehow got connected to HV 60 Hz. If you really are running
your coil in a chickenwire cage, it's effectively a faraday cage, and is
an electrically closed system, so connecting it to mains ground
shouldn't cause noise (in THEORY). For normal configurations, it has
been suggested to use an isolation choke between the mains and RF
grounds, to pass 60Hz fault currents but block HF noise.
