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.http://www.geocities.com/ferman30/AtomsDimTable.html

Correct but only if the equilibrium rule is respected
other wise it does move in line with the applied current

Would also like to point ouyt that we have bound electrons as part of
the diamagnetic
material of the radiator the other is an unbound electron or particle
that resides on the surface of the diagmatic
material. It is the charge of this unbound particle we are talking
about when levitated by the eddy current aqnd not the electons that
are bound within the material
