AUTO ANTENNA COUPLER (P/N 622-6471-002) - As Removed

The 622-6471-002 is an auto antenna coupler for aircraft HF communication systems. This component provides automatic impedance matching between the transceiver and airframe antenna, maintaining a 50-ohm interface for efficient RF power transfer. Installed near the antenna feed point, the coupler tunes during operation to minimize reflected power and optimize transmission efficiency.

The unit automatically adjusts to match varying antenna impedance across the HF frequency range. Installation and testing must follow the aircraft maintenance manual and applicable avionics documentation for your specific airframe.
