General Support Track Order. Terrestrial television or over-the-air television (OTA) is a type of television broadcasting in which the signal transmission occurs via radio waves from the terrestrial (Earth-based) transmitter of a TV station to a TV receiver having an antenna.The term terrestrial is more common in Europe and Latin America, while in Canada and the United States it is called over-the-air or simply broadcast. For example, a 1-meter . FM broadcasting is a method of radio broadcasting using frequency modulation (FM).Invented in 1933 by American engineer Edwin Armstrong, wide-band FM is used worldwide to provide high fidelity sound over broadcast radio.FM broadcasting is capable of higher fidelitythat is, more accurate reproduction of the original program soundthan other broadcasting technologies, CHAYKA, the Russian counterpart of LORAN, but still in use as of 2014.
