Re: electromagnetic wave fundamental frequency and harmonic series?



Original poster: Ed Phillips <evp@xxxxxxxxxxx>

The problem is that the circuit from the toroid to the surroundings and back to the coil's base ground is in series with the winding AC resistance. It is hard to tell how much current there is lost just to heat in the ground return path or might be radiated. I suspect very little is radiated, but the type of test I did could not determine that for sure.

A better test would be to run the secondary at Fo from a signal generator in say an open field and use a LF radio receiver. Just walk back and find out how far you get ;-)

One could probably figure it out pretty well with some thought as to how to calibrate everything in that simple case.

   Agree with all of that.
