In the Hertz apparatus the charges (electrons) have at the centre the
max velocity and the acceleration equal zero.
At ends the situation is opposite. So your answer should be: "the ends
radiate of course".
of course you are wrong. there is a smooth transition between the
center and the ends, that whole length radiates. you can't just look at
the boundry conditions, you have to consider the whole length.
Doesn't NEC use the method of moments (MoM) which deals
with total current and isn't total current maximum at the
feedpoint (middle) of a 1/2WL dipole where the maximum
acceleration of electrons is taking place?
