Yaesu RA144240A BNC Connector for FTA‑550 / FTA‑750 Radios

Yaesu RA144240A BNC Connector – Genuine Replacement Antenna Connector for FTA-550 / FTA-750 Radios | Radioworld UK


Trustpilot

The Yaesu RA144240A BNC Connector is a genuine OEM replacement part designed for the Yaesu FTA-550 and FTA-750 series airband transceivers.

This high-quality connector forms the base antenna fitting on the top of your radio and provides a secure, low-loss connection for standard BNC antenna mounts. Over time, connectors can loosen or corrode due to environmental exposure — replacing it with a genuine Yaesu RA144240A ensures your radio maintains optimal performance, reliability, and RF integrity.

Manufactured in Japan to Yaesu’s exacting standards, this connector is a direct replacement for the original factory-fitted BNC socket. It works seamlessly with the associated RA6180200 Collar (BNC) and RA084400A O-Ring to maintain proper antenna fitment and weather sealing.

Ideal for field engineers, aviation radio technicians, or amateur operators performing maintenance, the RA144240A restores your radio to its original specification and ensures dependable operation.
