Ron,
What you've come to understand is absolutely false except for the
special case of a long wire close to the ground. That special case
is called a Beverage antenna that radiates vertically polarized
radiation off the ends.
When you raise a long wire antenna more than about 0.05 wavelengths
above the ground, horizontal polarized radiation becomes dominant
and the radiation pattern always has a deep null off the ends.

Understand that a true "long wire" (greater than 1 wavelength) starts to be
directional off of its end (if fed at one end, that's the opposite end).
