Christoph, A while back someone on the US longwave reflector posted the result of an experiment. They took a receiver to the site of a high power Tesla coil operating at LF, I believe it was being driven at 175kHz. they expected to hear it at some distance but were surprised to find out they could only hear the Tesla coil at very short distances. It seems that a coil by itself is an extremely poor radiator at LF! It is unknown to me if there was any earth connection to the Tesla coil, perhaps only through the mains connection.
