. . . there is SOME radiation but it will be very small because
the coil is a most inefficient radiator because of its length
compared to the wavelength of the signal in it. . . .
If one operates a very large Tesla coil in the non-sparking mode,
at say 100 watts, and say that 5% of the energy is dissipated in
the form of electromagnetic radiation, where do you think the
remaining 95% goes?
I have done this.
Most of the energy is simply dissipated as heat being burned off in
the Secondary wire resistance. There are also losses involved with
the top capacitance and it's ground return path. Some of those
losses are probably RF, but it seems at least 90% of the energy is
lost to resistive heating.
