Thanks for that info, Tom.

If resonance is not necessary, then I need only one turn of .75 diameter to
make sure resonance is higher than my operating frequency. That would make
the coil with parasitic capacitance look inductive.

??? A single turn 3/4" diameter won't give you much reactance at 440.
Looks to me like if you used about three turns with that ID with a
total length around 1.5 inches, you'd be a lot better off. That'll be
about 300 ohms inductive reactance, shunted by enough parasitic
capacitance to come close to resonance (thus a higher net reactance).

Cheers,
Tom
