The Fourier coefficients for the Power Spectra decrease as 1/(n^2), not

Hence, your 1500th harmonic is down 66 dB, not 33 dB.

Amen!

And given that you are coupling into some Gawd awful mismatched radiator
you can probably chop of at least another 30 or 40db.

Not all wires are bad radiators at all frequencies. Your assumption is
correct if you intend for the wire to radiate. My premise is correct if you
don't want it to. Nature always works against man's desires or more
correctly, man always works against nature.

Amen!
