Re: Tesla Coil Operation - was "Harmonics"



"Actually, once you get the wave propagating, the loss is pretty low.
The ELF
systems for sub communications run around 15 kHz carrier frequency and
have
remarkably low path loss. However, they put a megawatt into the antenna
to
radiate about a milliwatt.."

	There's a message there somewhere.  The antennas are incredibly
inefficient, as must be any antenna with dimensions small with respect
to a wavelength.
