ABSTRACT:
A portable device capable of being removably supported within the metal passenger carrying body of an automobile vehicle to receive high and low frequency short wave radio signals when the vehicle is in the line of sight area in which such signals are broadcast. The body of the vehicle becomes alternately charged by the broadcast electromagnetic signals, and as a result thereof emanates secondary electromagnetic waves. The present device is disposed adjacent to the interior surface of the body but electrically insulated therefrom. The device when so disposed has the secondary electromagnetic waves pass through a helically wound coil of wire that forms a part thereof, and the secondary waves in so doing generating an electric current in the coil of sufficient magnitude as to be subsequently amplified by the radio and transformed into audible sound waves.
