Oh yes, the important spacing--we agree on that alright (the rest too--I see
that physical/electrical length as important to--but "electrical length" and "magnetic field shape" are related on an almost linear scale), but what is "in" that "spacing"--now there is the nut of this... that "magnetic field" is not a "proton projection" and my antenna does not "glow"--and that "space" ain't no wire--or is it?
