I've got 763 turns in my design. I'm limited in this case by
availability (read: budget) of 24-gauge wire. The design is wound on a
2.5" core, with a winding height of 18 inches. Its self-resonant
frequency is 915.55 kHz, and its quarter wavelength frequency is 493.38
kHz. Its self-capacitance is 6.37 pF, and I'll be resonating it at
quarter wavelength with a 15.57 pF toroid.
