Heh heh - yes I did say the wire needed to be a half-wave above ground - that would negate the capacitive coupling. In practical terms the antenna would be matched to the (usually 50ohm) transmitter output with an 'Antenna Matching Unit', basically an impedance matching tank circuit. The losses...
There are numerous amateur radio publications about VLF, and amateurs have allocations in this segment of the spectrum - 500KHz is popular worldwide. For a half wave dipole at this frequency, the length would need to be 660m long, (c/freq) times the velocity factor of the wire, and, to be...
Ferrites are commonly used in RF applications - mainly to choke off interference. Have a look at http://audiosystemsgroup.com/publish.htm - I'm sure you'll find plenty to interest you there.
I read the following article with interest:

What is not apparent (to a layman such as myself) is the application for such an antenna. I was quite excited to think that if light can be gleaned by an antenna, and indeed be 'magnified' by...
