WWII Antenna Coupling Unit CU-92/APN (NIB Wrapped)

Original WWII-era Antenna Coupling Unit CU-92/APN, still in original military packaging with intact label (dated 1945). Used in aircraft radar/communication systems to match antenna impedance and optimize signal performance. Packaging marked with stock number and handling instructions. Unit remains wrapped and untested—sold as found. Outer paper shows age, staining, and storage wear. Excellent untouched Signal Corps/Navy aviation electronics piece with strong collector appeal.
