TNC F CLAMP for LMR400/RG8/RG11/RG213/RG393 Cable

Description

The TNC (Threaded Neill-Concelman) series is a high-reliability RF interface designed to maintain electrical continuity in environments subject to high vibration and shock. This female (jack) variant is specialized for the 10mm (0.400″) heavy-duty cable class, providing a precision termination for ultra-low-loss LMR400, military-spec RG213, and high-temperature RG393. It is the essential connector for equipment interfaces and cabinet transitions that demand high power handling and low attenuation over long cable runs.

Unlike crimp-style connectors, the clamp termination design utilizes a high-torque compression nut and internal gaskets to secure the cable’s outer conductor and braid. This allows for a professional-grade assembly using standard hand tools, making it the superior choice for field maintenance, remote tower sites, and custom-length cable assemblies where specialized heavy-duty crimping tools are unavailable. Manufactured with a reinforced nickel-plated brass body and premium PTFE (Teflon) insulation, it delivers consistent 50-Ohm performance and low VSWR up to 11 GHz.

Key Technical Advantages

• Field-Serviceable Clamp Design: Enables high-quality, repeatable terminations without the need for specialized crimping tools, facilitating rapid onsite maintenance and shipboard RF repairs.

• Large-Diameter Precision Match: Specifically calibrated for 0.400-inch to 0.430-inch OD cables, ensuring an optimized electrical path and high-strength mechanical stability for heavy-gauge lines.

• Vibration-Proof Threaded Interface: The 7/16-28 external threads ensure a secure, locked connection when mated with TNC male plugs, preventing signal intermittent issues in high-shock environments.

• Superior Environmental Protection: The integrated compression seal and internal gaskets provide a moisture-resistant barrier, essential for outdoor antenna systems, maritime deployments, and industrial enclosures.

• High-Power Handling: Precision-machined to support the high wattage and low attenuation characteristics of LMR400 and RG213, ensuring signal integrity across high-frequency bands.
