Icom OPC-1147N Control Cable NOT FOR USE WITH M803

The Icom OPC-1147N Control Cable is a professional-grade shielded interconnect designed for amateur radio operators and communications technicians who require reliable command and control between compatible Icom equipment. This ten-meter cable specifically interfaces with the Icom AT-140 antenna tuner, enabling seamless integration into single-sideband and amateur radio station configurations. The extended cable length accommodates flexible equipment placement, making it ideal for base stations, mobile installations, and field operations where distance between control units and tuning components demands a robust, noise-resistant connection.

Built with shielded construction, the OPC-1147N minimizes electromagnetic interference and RF noise that can degrade tuning precision and control signal integrity—critical factors in high-frequency amateur radio work. The cable arrives fully terminated with industry-standard connectors, eliminating the need for custom crimping or adapter assemblies and reducing installation time. At approximately three pounds, the cable maintains proper weight balance during routing through equipment racks or along antenna mast pathways, while shielding materials protect against cross-talk from adjacent power supplies and transmission lines common in radio shacks.

Radio enthusiasts, emergency response teams, and technical service personnel benefit from this cable's proven compatibility with AT-140 antenna tuner systems, where control reliability directly impacts impedance matching and power transfer efficiency. The ten-meter length accommodates antenna tuners mounted at mast bases or in weatherproof enclosures distant from radio transceivers. Note that this cable is not compatible with the M803 model; users must verify their tuner revision before ordering to ensure proper fit and functionality within their existing Icom station infrastructure.
