Thanks, Graham. Looks interesting, will have a proper read later.

AND Warren, there are those who hold that the only place from which we may observe our universe is from one of the other(s)!

At this point in the narrative the little folk like me retreat deeply into papers and books by the likes of Hawking and Penrose :>)))

Pat,

Of course, it also holds to be true that the "rest of the universe" that is the "other plate" of my capacitor is also the "other plate" of everyone else's similar capacitor and is the common circuit element to which we are all referenced!

Surely every conductor in the unit will have a difference in potential

Even in the legs of the FET. Although the potential will be extremely small.

Yes, of course that's correct.

I should have written that with a fiber optic cable instead of the coaxial
cable, all circuit elements are coupled to the field at _almost_ the same
place, and thus are at _almost_ the same potential, and thus _almost_ no
signal will come out: very much less than with the coax still in place.

B.t.w., some mini-whips are built using a metal can as the probe, with
the entire electronics inside the can; such an arrangement would get
quite close to zero output when the coax is replaced by the fiber optics.

Anyway, it was originally claimed that the functioning of the mini-whip
does not depend on the coaxial cable; I just intended to explain why I
think it does.
