Current is always zero at the end of a radiator of any length.

Maybe Frank but it never came to a stop!!!!.
When you look at it as not being equilibrium one must show the sharges
moving to the ends of the radiator

The charges (electrons) do not realy move. They vibrate
at the applied E-field frequency. The charge displacement,
depending on frequency; for example at 10 MHz, is of the
order of 10 atomic diameters -- approximately 2*10^(-9) m.
