N M CLAMP for LMR400/RG8/RG11/RG213/RG393 Cable

Description

The N-Type connector is the premier choice for infrastructure-grade RF applications, valued for its high power handling and low attenuation at microwave frequencies. This male (plug) variant is specialized for the 10mm to 11mm (0.400″ – 0.430″) large-diameter cable class. Unlike crimp-style connectors which require specialized large-format hydraulic tools for thick-gauge cables, this variant utilizes a mechanical clamp termination system. This design employs a heavy-duty internal compression sleeve, pressure washers, and a rear fastening nut to secure the cable braid, providing an airtight, high-strength connection that can be assembled on-site with standard wrenches.

The clamp design is ideal for remote tower sites and outdoor installations where field-serviceability is critical. It ensures a superior mechanical and electrical bond by applying uniform pressure across the heavy-gauge outer conductor of cables like LMR400 or RG213. Manufactured with a reinforced nickel-plated brass body and premium PTFE (Teflon) insulation, it delivers consistent 50-Ohm performance and low VSWR up to 11 GHz. The integrated O-ring seals and compression-fit design provide an exceptional moisture barrier, making it essential for outdoor cellular towers, long-range antenna arrays, and marine communication systems.

Key Technical Advantages

• Large-Diameter Precision Fit: Specifically calibrated for the 0.400-inch OD cable family, ensuring maximum pull-off resistance and an optimized electrical transition for heavy-duty coaxial lines.

• Field-Installable Design: The clamp-style assembly allows for high-integrity terminations without the need for specialized large-diameter crimping tools, facilitating on-site repairs and custom jumper builds.

• High-Power Capacity: Precision-engineered to handle the significant power levels typical of large feeder lines, maintaining thermal and electrical stability under heavy loads.

• Vibration-Proof Threaded Interface: The 5/8-24 threaded coupling provides a secure, locked connection that resists loosening in high-wind or high-vibration outdoor environments.

• Rugged Environmental Protection: Features integrated gaskets and O-rings to provide an IP-rated seal, protecting the cable’s internal dielectric from moisture ingress and corrosion.
