RF *IS* AC.

Yes. But RF CURRENT is: " "Electric currents that oscillate at radio
frequencies have special
properties not shared by direct current or alternating current of lower
frequencies. The energy in an RF current can radiate off a conductor into
space as electromagnetic waves (radio waves); this is the basis of radio
technology."

Now are also ULF transmitters (30Hz). So the above is not precise.
What decide that "an RF current can radiate off a conductor into space"?
