Since the forward current and reflected current are equal
in magnitude and opposite in phase at the ends, they act
like transmission line currents and the magnetic fields
cancel at the ends. They are in phase at the feedpoint -
hence the maximum radiation at that point.


See what Richard Harrison wrote:
"At the open circuited ends of a resonant
antenna there is almost double
the forward voltage but zero total current due to cancellation of the
forward and reflected currents at the open circuit. At the open circuit
in the wire, all the energy in the wave is transferred to the electric
field."


What I wrote agrees with what Richard H. wrote and vice versa.
