Richard Clark, KB7QHC:

Part of this debate has ignored that all resonant circuits can be
analyzed as both parallel and series. That is, barring your and my
observations.

To force the parallel resonant observation upon the quarterwave
vertical, all that need be done is to move the drive from the base to
the tip. The same current distribution will be observed, the same
radiation characteristic will persist, and as such nothing has really
changed.


Uh, huh, NOT!

The top hat does not grace a full
quarterwave vertical as it would be redundant to that mission. Such
an addition would end up instead throwing the design into a quasi
3/8ths tuning, or such, to dubious purpose.


Uh, huh.
Quasi 3/8 tuning (with 1/8 radials) provides 50 ohm impedance, no need for
matching junk, lowers tha angle and provides increase in gain. Dubious? Not to
me.

Logically, the addition of more
capacity does not lead to resonance.


Oh no?

Yuri, K3BU
