TNC M RA CLAMP for LMR240 Cable

Description

The TNC (Threaded Neill-Concelman) series is a ruggedized version of the BNC interface, utilizing a threaded coupling to ensure constant electrical contact in high-vibration environments. This specialized Right Angle (RA) variant is optimized for the 6.1mm (0.240″) cable class, specifically low-loss LMR240. By orienting the cable exit at 90 degrees, it allows for streamlined cable routing in shallow enclosures and behind-the-panel mounts, protecting the cable’s internal dielectric from stress-induced signal degradation.

Unlike crimp versions, the clamp termination design utilizes a high-precision compression nut and internal gaskets to secure the cable’s outer conductor. This enables a professional, airtight assembly using standard hand tools, making it the preferred choice for onsite antenna configuration and maritime repairs. Manufactured with a heavy-duty nickel-plated brass body and premium PTFE (Teflon) insulation, it delivers stable 50-Ohm impedance and low VSWR up to 11 GHz, supporting the high-bandwidth requirements of modern cellular and wireless backhaul systems.

Key Technical Advantages

• 90° Space-Saving Profile: Ideal for installations behind equipment panels or inside compact mobile radio racks where a straight connector would exceed the depth limit or cause cable kinking.

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

• LMR240 Precision Match: Specifically calibrated for 0.240-inch OD low-loss cables, ensuring an optimized electrical path and high-strength mechanical stability.

• Vibration-Proof Threaded Interface: The 7/16-28 threaded mechanism ensures a secure, locked connection that outperforms bayonet-style connectors in high-shock or outdoor applications.

• Superior Environmental Sealing: The integrated compression seal provides a moisture-resistant barrier, shielding the cable’s internal conductors from corrosion and oxidation in harsh environments.
