Yep, it's my digital logic in action. :-) If there's no end,
then there cannot be reflections from the ends. And please
note that I am not saying that the characteristic impedance
of a dipole is constant all up and down the line. I'm only
concerned about the apparent characteristic impedance at
the feedpoint, i.e. Vfor/Ifor.

Consider an open circuit transmission line. At 1/4WL, it
exhibits a very low impedance. At 1/2WL it exhibits a very
high impedance. As the transmission line length is increased
to infinity, because of losses, the "stub" impedance will spiral
into the Z0 characteristic impedance point. A similar concept
should apply to a dipole.
