We haven't moved forward a bit on that first sentence of the other
post which is " what created the reflecting voltage" of this resonant
radiator when it is a fractional wavelength or a electrically full wave length?

The characteristic impedance of the horizontal wire above ground is in
the neighborhood of 600 ohms. The "load" impedance at the end of the
wire can be considered to be infinite. The reflection coefficient at
the tip of a dipole is 1.0, i.e. all the forward voltage is reflected
in phase. This is true no matter what the length of the dipole. The
round trip delay that the forward wave makes can be used to get a fair
approximation of the feedpoint impedance using transmission line
equations and assigning an appropriate value to the alpha loss factor
which not only includes real losses but also "losses" due to
radiation.
