How do tv programs come to the tv via antenna?
user
Television broadcasting involves a method by which a television station transmits a signal, that the television receivers can pick up with the use of an antenna.  That way, a person can view a television program without having to sit in front of the television.  And television programing continues on for hours, while a person can do other things at the same time.
