Product Description

The ac31d-2 is an HF antenna box that houses the antenna coupler, RF feedthrough, and interconnecting cabling for HF communication systems operating in the 2–30 MHz frequency range. This enclosure protects sensitive RF components while providing impedance matching between the transceiver and the airframe-mounted antenna. Typically installed in the avionics bay or tail section, the box mounts securely to the aircraft structure and facilitates proper signal transmission.

Installation follows aircraft-specific AMM procedures and FAA AC 43.13-2B guidance. Verify compatibility with your aircraft's IPC before installation.

Please note: Product descriptions are provided for informational purposes. Always refer to your aircraft's Illustrated Parts Catalog (IPC) to verify part compatibility and specifications.
