... 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 |
