Icom OPC440 Microphone Extension Cable (16.4ft)

Microphone Extension Cable 16.4-foot (5m) RJ-45 modular extension cable for mobile two-way radios. The Icom OPC440 (also designated as OPC-440) is a genuine OEM microphone extension cable designed to extend the operating reach between a mobile radio transceiver and its handheld palm microphone. Measuring 5 meters (16.4 feet) in length, the Icom OPC440 features high-quality RJ-45 modular connectors (male to female) that provide a secure, plug-and-play connection without loss of audio quality or control signal transmission. Designed for fleet vehicles, public safety trucks, agricultural machinery, and desktop base station setups, the Icom OPC440 solves complex mounting challenges. In many commercial and emergency vehicle installations, the radio chassis is mounted under a seat, in a trunk, or inside a console compartment, placing the main microphone jack out of easy reach. The Icom OPC440 allows installers to route the microphone line discreetly through the cabin, positioning the hand microphone right where drivers or dispatchers need it most. Engineered with heavy-duty strain relief boot covers and durable outer jacketing, the Icom OPC440 withstands constant vehicle vibration, temperature shifts, and physical flexing. The precision-molded RJ-45 modular plugs ensure stable latching, preventing accidental disconnects during active shifts or off-road driving.
