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

Description

The TNC (Threaded Neill-Concelman) series is a high-reliability version of the BNC interface, utilizing a threaded coupling to ensure signal continuity in environments subject to high shock and vibration. This specialized Right Angle (RA) variant is designed for installations where clearance is minimal and cable management is critical. By orienting the cable exit at 90 degrees, it prevents stress on the cable dielectric and avoids hazardous kinking, which is essential for maintaining the performance of low-loss cables like LMR195 and high-temperature RG142.

Unlike crimp versions, the clamp termination design utilizes a high-torque compression nut and internal gaskets to secure the cable’s outer conductor. This allows for professional-grade, airtight assembly using standard hand tools, making it the preferred choice for field repairs, maritime environments, and custom-length cable assemblies. 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.

Key Technical Advantages

• 90° Space-Saving Geometry: Significantly reduces the depth required behind panels and equipment racks, ensuring a clean installation in compact mobile radio and aerospace enclosures.

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

• Vibration-Proof Threaded Interface: The secure 7/16-28 threaded coupling prevents signal intermittent issues, providing a more stable connection than bayonet-style alternatives in high-G applications.

• Superior Environmental Sealing: The integrated compression seal and clamp mechanism provide a moisture-resistant barrier, protecting the cable’s internal shielding from corrosion in outdoor and marine deployments.

• High-Frequency Stability: Precision-machined to maintain consistent electrical performance up to 11 GHz, supporting advanced GPS, telemetry, and wireless data links.
