The 522-2931-004 is a Collins 179J-7 ADF sense antenna coupler that resolves the 180-degree ambiguity inherent in loop antenna navigation. This component supplies the omnidirectional sense signal path in L/MF band ADF systems, working alongside the directional loop element to provide accurate bearing information. Installed between the sense antenna element and the ADF receiver, it matches and conditions the incoming signal for proper receiver processing.
Installation and testing must follow the aircraft's avionics maintenance manual and FAA-approved technical data. Complies with FAA TSO-C41 standards for ADF equipment.
