Wrong, AC at ANY frequency can radiate off a conductor into space as
electromagnetic waves.

AC is in oscillating circuit (closed circuit). RF current is in an antenna
(open circuit).

Wrong again, moron.

AC means Alternating Current as opposed to DC or Direct Current.

RF means Radio Frequency and is generally used to the AC that is being
received by a receiver or transmitted by a transmitter.

None of these terms has anything to do with open or closed circuits.

You are an ignorant, babbling, ineducable idiot who knows absolutely
NOTHING about how anything works.
