Default Contrary current flow within a radiator

Assuming that significant r-f current exists at the center of a
radiating conductor, where does it go when it reaches the end of that
conductor?

RF



It doesn't "go" anywhere. As the conductor (and it's return path;
ground or whatever) is resonant, the generator sees it as a resistor.
The current is "absorbed" by this "load". But instead of pure heat, an
electromagnetic field ensues. Nothing goes anywhere.
