	One infers it is the freq at which the thing goes 1/4 wave
	resonance.  relatively easily determined.  First (and lowest)
	of the self resonant modes.

	(A classical solenoid, for controlling vales & such hasn't
	got one, being too lossy.  A single layer coil (eg crystal set,
	tesla primary or secondary, or flat wound coil) will resonate.)
