N M RA CLAMP for 1/2″ Feeder Cable

Description

The N-Type connector is the premier choice for infrastructure-grade RF applications, valued for its mechanical robustness and environmental durability. This Right Angle (RA) variant is specialized for the 1/2″ corrugated cable class, which is the most common size for high-performance jumpers connecting primary feeder lines to antennas. The 90-degree configuration is essential for tight-clearance tower mounts and cabinet routing, allowing for clean cable management without exceeding the cable’s minimum bend radius.

This connector utilizes a mechanical compression clamp termination specifically designed to grip the solid, annularly corrugated copper outer conductor. This ensures an airtight, ultra-low-resistance electrical bond that maintains superior Passive Intermodulation (PIM) performance over decades of deployment. The clamp design is essential for field-serviceability, allowing for precision terminations on-site using standard wrenches. Manufactured with a reinforced tri-metal (Albaloy) plated brass body and premium PTFE (Teflon) insulation, it delivers consistent 50-Ohm performance and low VSWR up to 8.8 GHz. The integrated O-ring gaskets provide an IP68-rated moisture barrier, ensuring total reliability in exposed outdoor environments.

Key Technical Advantages

• Compact 90° Routing: Significantly reduces the depth required for connections, facilitating high-density cable management on tower tops and within equipment enclosures.

• 1/2″ Corrugated Cable Match: Specifically engineered for the annular corrugation profile of 1/2″ cables, ensuring maximum surface contact for superior electrical conductivity and mechanical pull-off strength.

• Low-PIM Performance: The precision-machined clamp interface minimizes non-linearities, a critical requirement for modern 5G, LTE, and multi-carrier wireless networks to prevent signal interference.

• Field-Installable Design: The mechanical compression system allows for high-integrity assembly on-site using standard wrenches, facilitating efficient jumper fabrication and system maintenance.

• Rugged Environmental Sealing: Features multiple integrated gaskets and O-rings to provide a complete weather-proof seal, protecting the cable dielectric from moisture ingress and oxidation.

Key Features

• Interface Type: N-Type Male (Plug) Right Angle (90°) with standard 5/8-24 threaded coupling.
