Icom OPC-1147N Shielded Control Cable for AT-140 and Transceiver 32 ft (10 mts)

The Icom OPC-1147N is a shielded control cable designed to establish a reliable command and communication link between a compatible transceiver and the AT-140 HF automatic antenna tuner. Spanning a generous length that accommodates real-world marine and fixed-station installations, this cable allows the tuner and transceiver to exchange control signals seamlessly, enabling the automatic tuning functions that professional operators depend on. The shielded construction is central to its value: by enclosing the signal conductors within a protective outer layer, the cable resists interference from the electrically demanding environments found aboard vessels and in densely equipped communications stations. For professional installers, the OPC-1147N removes the guesswork of sourcing a generic substitute — it is purpose-engineered to integrate directly with the AT-140, ensuring that control signaling between components behaves as the system was designed to perform. The result is a clean, interference-resistant installation that supports dependable, hands-free antenna tuning across demanding operating conditions.

Key features & benefits

• Purpose-Built System Integration — Engineered specifically to connect the AT-140 automatic antenna tuner to a compatible transceiver, ensuring the control interface functions exactly as the system architecture intends without improvised adapters or workarounds.
• Shielded Construction for Signal Integrity — The cable's shielding layer guards control signals against electromagnetic and radio-frequency interference, which is particularly critical in the congested electrical environments of marine vessels and professional communications installations.
• Professional-Grade Cable Length — The extended run length provides installers the routing flexibility needed to separate the transceiver and antenna tuner across a vessel or facility without compromising signal quality or requiring additional extensions.
• Icom OEM Quality Assurance — As a genuine Icom accessory, the OPC-1147N is manufactured to the same standards as the primary equipment it supports, giving operators and system integrators confidence in long-term reliability and consistent performance.
• Simplified, Correct Installation — Using the correct manufacturer-specified cable eliminates compatibility uncertainty during installation, reduces commissioning time, and ensures that automatic tuner functionality operates as intended from the moment the system is powered on.
