Aircraft VLF/LF/MF Window Antenna Receiving System.
Abstract
The patent application describes apparatus for receiving the horizontal and vertical electric field components of incoming VLF, LF, and MF (10 KHz to 3000 kHz) signals that is easily portable and installed within minutes aboard aircraft with windows. A sheet of metal or matrix of interconnecting wires is placed against the inside surface of non-conducting windows on each side of the aircraft fuselage and used as the receiving antennas. The voltage sum of the two window antennas is proportional to the vertical electric field. The voltage difference of the two window antennas is proportional to the horizontal electric field particularly when the antennas are forward or to the rear of the wings extending from the fuselage.
