Your intuitive theories may not support this, Arthur, but haven't you
noticed that your linear, dipole antennas (whether "short" or 1/2-wave)
transmit and receive very poorly in the directions of their longitudinal
axis? In fact, radio direction finders make use of this proven reality of
radiation physics.

How do you explain this, if you believe that the radiation pattern/gain of a
dipole is not very low in those directions, as in the nulls of a figure 8,
and as easily measured for these antenna configurations on a good test
range?

Please post your supporting math(s).

Ofcourse there is no radiation off the ends. What ever is sitting on
the antenna
can only fall off one side or the other. As far as the math goes you
are not
conversant enough with math to get involved. You could redeem your
self by
pointing out the deliberate mistake made by Dr John E Davis and become
an overnight
guru. Just think up another lie nobody will challenge you!
