	Ooooops.
	Fergot to mention:
		I have seen brief mention, somewhere, of HAM Ops using
		Slinkys as adjustable, field expedient, continuously
		loaded antennas.

	Someone may be thinking:
		Steel.  Inductive Losses.
	Turns out with the RF flowing mostly on the surface, losses
	are not real dependent on conductor materials.  And these
	are _expedient_, rather than optimized....)
