3 WAY FEEDER CLAMP FOR 7/8″ FEEDER CABLE

Description

The 3-Way Feeder Clamp for 7/8″ Feeder Cable is a heavy-duty hardware solution designed to handle the substantial combined weight and wind load of triple large-diameter transmission lines. It is specifically sized to fit the outer diameter of standard 7/8″ corrugated (annular or helical) coaxial cables, such as LDF5-50A, AVA5-50, or equivalent 50 Ohm feeder lines. The assembly consists of three high-impact, UV-resistant polypropylene (PP) saddles secured within a reinforced SUS304 stainless steel C-bracket.

This clamp is essential for 3-sector antenna deployments and high-capacity multi-carrier sites where three primary feeder runs must be routed efficiently along the same path. By providing a secure, contoured grip for three cables simultaneously, it ensures maximum mechanical stability and prevents signal-degrading cable movement or dielectric deformation. The design is optimized for high-vibration and high-wind environments, ensuring all cables remain locked in place during extreme weather. The high-grade stainless steel construction provides a maintenance-free lifespan in corrosive or coastal regions, while the high-density configuration significantly reduces the mounting footprint on crowded tower members.

Key Technical Advantages

• Triple-Cable Density: Secures three 7/8″ primary feeder runs within a single mounting point, maximizing the available space on tower members, monopoles, and cable ladders.

• Precision 7/8″ Fit: The plastic hanger inserts are molded to the exact outer diameter of 7/8″ corrugated cable (approx. 27mm-28mm), providing a secure, non-slip grip that protects the cable’s structural integrity.

• Maximum Corrosion Protection: All metallic components, including the C-bracket, threaded rod, and fasteners, are made from SUS304 stainless steel to resist rust and environmental decay.

• High-Impact UV Stability: The hanger inserts are formulated with industrial-grade UV stabilizers to maintain structural flexibility and strength under continuous solar radiation and extreme thermal cycling.

• Engineered for Extreme Loads: Specifically designed to support the significant vertical weight and cumulative wind surface area of three 7/8″ feeder runs without mechanical failure.

Key Features

• 3-Way Configuration: Engineered to support three independent 7/8″ primary feeder cable runs per clamp assembly.

• 7/8″ Feeder Compatibility: Optimized for standard 7/8″ corrugated cables, including low-loss, high-power, and fire-retardant transmission lines.

• Reinforced C-Bracket: A heavy-duty stainless steel frame designed to maintain constant tension across all three cable positions under heavy wind and ice loading.

• Comprehensive Hardware Kit: Includes three UV-resistant plastic saddles, a stainless C-bracket, an M10 threaded rod, and all necessary lock washers and hex nuts.

• Modular Infrastructure Ready: Designed for immediate attachment to standard tower angle adapters, round members, or monopole brackets.
