There's another interesting thing about very fat antennas.

Again considering them as transmission lines, their Zo is quite low
and so the input, or end impedance of a half-wave dipole is relatively
low.

Thus it is possible to place two half-wave dipoles in series and feed
them in the middle. (In the same way as feeding one half-wave dipole
in the middle).

What does the radiation pattern of a full-wave, exceedingly fat dipole
look like? Can the modelling programs cope? What's the feedpoint
impedance at resonance? What's the bandwidth?

What about a 4 or 5-to-1 ratio for Length / Diameter?
