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

		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....)
