The dipole is fed with open wire line, so that it can be used on other
bands. RF ammeters in the remote automatic antenna tuner suggest the
currents in the two feed wires are substantially equal. One leg of the
dipole runs over the house, and my suspicion is that the field produced by
it induces currents in the house wiring. probably ferrite chokes on the
feed in and out of the RCD are the best answer, although the form of the
switchbox and its location make that a little difficult physically.

Tempting, but somewhat illegal over here. The nanny state, you know!
