aerial defined in 1939 yearaerial - Aerial (antenna);
aerial - In radio and television engineering, an elevated conductor or group of conductors from which high-frequency electro-magnetic waves are transmitted, or by which they are received. The simple aerial used for broadcast receiving sets consists usually of a horizontal wire, with or without a vertical continuation, supported on insulators. Other forms are frame aerials used in portable receivers or direction finders; beam or curtain aerial systems on directional transmitting stations; and similar systems used for the reception of radiations from one direction only. An aerial functions as a transmitter of radio waves when high-frequency oscillating currents are fed into it; similarly, it converts electro-magnetic waves received by it into oscillatory currents, which are again converted in the receiver into audible or visible signals. See Radio; Television.
