Changing the phase of an AC voltage by 180 degrees
changes the amplitude from positive to negative or
from negative to positive. That's what is happening
in the ASCII graphic that you drew.

o.k. i was a bit to fast. But if we see the complete pictu
(hope it comes across in the original bits)

We see here, as in all antennabooks, at the leftside the voltage and current are in phase,
But in the right side the voltage and current are in antiphase, hence my conclusion that
the antenna must be reactive ! From your explanation at 180 degrees, why doesn't
current at the right side flip over then ? Should be.
