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<= br> 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.
