N M CLAMP for 1/4″ Feeder Cable

Description

The N-Type connector is the industry standard for high-reliability RF infrastructure, valued for its durability and excellent power handling. This male (plug) variant is specialized for the 1/4″ corrugated cable class, specifically optimized for high-performance feeder lines. Unlike connectors for flexible braided cables, this variant utilizes a mechanical compression clamp termination designed to grip the solid, annularly corrugated copper outer conductor. This ensures an airtight, low-resistance electrical bond that maintains superior Passive Intermodulation (PIM) performance.

The clamp design is essential for field-serviceability, allowing for precision terminations without the need for specialized hydraulic crimping tools. It provides a permanent mechanical seal that prevents the cable from twisting or pulling out under stress. Manufactured with a reinforced nickel or tri-metal (Albaloy) plated brass body and premium PTFE (Teflon) insulation, it delivers consistent 50-Ohm performance and low VSWR up to 18 GHz. The integrated O-ring gaskets provide an IP-rated moisture barrier, ensuring long-term reliability in exposed outdoor environments and high-density wireless installations.

Key Technical Advantages

• Corrugated Cable Precision: Specifically engineered for the 1/4″ annular corrugation profile, 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 multi-carrier cellular and LTE infrastructure to prevent signal interference.

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

• Rugged Environmental Sealing: Features multiple integrated gaskets and O-rings to protect the cable dielectric and internal contact from moisture ingress and corrosion.

• Vibration-Proof Threaded Interface: The 5/8-24 threaded coupling ensures a secure mechanical lock, maintaining signal stability in high-wind and high-vibration outdoor environments.
