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

Description

The TNC (Threaded Neill-Concelman) series provides a secure, threaded alternative to the BNC interface, making it essential for environments subject to heavy vibration. This male (plug) variant is specialized for the 5mm (0.195″) cable class, accommodating flexible RG58, high-temperature RG142, and low-loss LMR195/LMR200 cables. Unlike crimp connectors, the clamp termination design utilizes a compression nut and internal gaskets to secure the cable’s outer conductor, allowing for a professional, airtight assembly without the need for specialized crimping tools.

This connector is ideal for field repairs and custom-length cable assemblies where signal integrity and mechanical strength are paramount. Manufactured with a heavy-duty nickel-plated brass body and premium PTFE (Teflon) insulation, it ensures low signal loss and stable impedance up to 11 GHz. The clamp system provides a superior 360-degree ground connection and exceptional moisture resistance, protecting the cable’s internal dielectric from environmental degradation in outdoor or maritime deployments.

Key Technical Advantages

• Field-Serviceable Clamp Design: Enables high-quality termination using standard hand tools, making it the preferred choice for remote field maintenance and onsite equipment configuration.

• Vibration-Proof Threaded Interface: The 7/16-28 threaded coupling ensures a constant mechanical and electrical connection, preventing signal cutouts in high-shock or high-vibration applications.

• 5mm Cable Precision Match: Specifically calibrated for the RG58 and LMR200 cable family, ensuring an optimized electrical path and high-strength pull-off resistance.

• Superior Environmental Protection: The integrated compression seal and clamp nut provide an airtight barrier against moisture and dust ingress, essential for outdoor antenna systems.

• High-Frequency Performance: Engineered to maintain low VSWR and consistent 50-Ohm impedance up to 11 GHz, supporting a wide range of telemetry, GPS, and wireless data links.
