At the top of a monopole, and at the ends

generate very little of the total EM radiation from these antennas.

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.

EM means elecro- magnetic. Radiation can start from any of them, See what

the forward voltage but zero total current due to cancellation of the

in the wire, all the energy in the wave is transferred to the electric
field."
