Hi Walt,
I do not have personal experience, but from listening to RF feedback through
poorly shielded audio amplifiers, I would try to keep the transmitting
antenna as far away from the implant as possible. I'd be especially careful
of handitalkies with their antennas attached directly to the handitalkie.
