No, you have it wrong again - the current must be zero at the ends, there is
nowhere for it to go, and there cannot be acceleration of charge is there's
no current. Please go away and read some books and the NEETS module to
which I provided the link.

Hi Chris,

This mistake is being compounded daily, so it seems. The "absence" of
current on any particular portion of the antenna is the superposition
of two currents flowing - hence the term "standing wave antenna."
Hence there is something of a paradox that where two currents reside
(the metal elements are continuous and conductive) it is said no
current flows. There is a correlation between this superposed
solution and the pattern of the far-field pattern but that does not
lead to the conclusion that there is no "acceleration" of charge at
the ends. After-all, the abundant alternating voltage at those same
ends is also charge, n'est pas? It could be as easily argued that
superposed voltage nodes also define the pattern of the far-field
pattern.
