N M CLAMP for 7/8″ Feeder Cable

Description

The N-Type connector is the premier choice for infrastructure-grade RF applications, valued for its high power handling and environmental durability. This male (plug) variant is specialized for the 7/8″ corrugated cable class, which serves as the backbone for high-capacity telecommunications systems. Unlike connectors for flexible braided cables, this variant utilizes a mechanical compression clamp termination specifically designed to grip the heavy-gauge, 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 on large-diameter cables, allowing for precision, high-strength terminations without the need for specialized hydraulic crimping tools. It provides a permanent mechanical seal that prevents the heavy cable from twisting or pulling out under extreme environmental stress or tower vibration. 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 5 GHz (optimized for feeder frequencies). The integrated O-ring gaskets provide an IP68-rated moisture barrier, ensuring total reliability in exposed outdoor environments and high-capacity wireless installations.

Key Technical Advantages

• 7/8″ Corrugated Cable Match: Specifically engineered for the large-scale annular corrugation profile of 7/8″ cables, ensuring maximum surface contact for superior electrical conductivity and extreme pull-off strength.

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

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

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

• Vibration-Proof Threaded Interface: The 5/8-24 threaded coupling provides a secure mechanical lock with high torque capability, ensuring stable performance in high-wind and high-vibration outdoor environments.
