N M CLAMP for 1-1/4″ Feeder Cable

Description

The N-Type connector is the premier choice for infrastructure-grade RF applications, valued for its extreme durability and high power handling. This male (plug) variant is specialized for the 1-1/4″ corrugated cable class, which is utilized in high-performance networks to minimize signal attenuation over long vertical runs. Unlike connectors for flexible braided cables, this variant utilizes a heavy-duty mechanical compression clamp termination specifically designed to grip the large-scale, solid annularly corrugated copper outer conductor. This ensures an airtight, ultra-low-resistance electrical bond that maintains superior Passive Intermodulation (PIM) performance under high-power loads.

The clamp design is essential for field-serviceability on very large-diameter cables, allowing for precision 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, such as ice loading or high-wind 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 4 GHz. 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

• 1-1/4″ Corrugated Cable Match: Specifically engineered for the massive annular corrugation profile of 1-1/4″ 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.
