TNC F CLAMP for RG58/RG142/LMR195/LMR200 Cable

Description

The TNC (Threaded Neill-Concelman) series is a high-reliability RF interface that utilizes a threaded coupling to ensure stable electrical contact in environments subject to high vibration and shock. This female (jack) variant is specifically optimized for the 5mm (0.195″ – 0.200″) cable class, providing a precision fit for versatile cables ranging from standard RG58 and high-temperature RG142 to low-loss LMR195 and LMR200. It is an essential component for equipment interfaces and cabinet transitions where signal integrity and mechanical security are paramount.

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, shipboard repairs, and custom-length cable assemblies where specialized crimping equipment may not be accessible. Manufactured with a heavy-duty 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 field RF repairs.

• Universal 5mm Cable Fit: Specifically calibrated for the 0.195 to 0.200-inch OD cable family, ensuring an optimized electrical path and high-strength mechanical stability.

• 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-Frequency Stability: Precision-machined to maintain consistent electrical performance and low insertion loss up to 11 GHz, supporting modern Wi-Fi, GPS, and cellular frequencies.
