EIA FLANGE for 1-5/8″ FEEDER Cable

Description

The EIA (Electronic Industries Alliance) Flange series represents the pinnacle of high-power RF interconnection, designed to handle the massive voltage and current loads associated with high-wattage transmission systems. This variant is specifically engineered for 1-5/8″ Feeder (Corrugated) cable, the standard for long-run, low-loss vertical feeders on broadcast towers and cellular sites. The bolt-circle mounting system provides a rigid, high-torque connection that far exceeds the mechanical and electrical stability of threaded interfaces like 7/16 DIN or 4.3-10 in high-power applications.

Maintaining a precise 50-Ohm impedance, this connector is optimized for Low PIM (Passive Intermodulation) to prevent interference in complex multi-carrier environments. It features a high-performance internal spring contact system for the 1-5/8″ inner conductor and a robust mechanical clamp for the corrugated outer conductor. Manufactured with silver-plated or tri-metal (white bronze) plated brass, it ensures maximum conductivity and a gas-tight seal when used with O-ring gaskets. This allows the system to be pressurized with dry air or nitrogen, critical for preventing moisture ingress and internal arcing in outdoor high-power transmission lines.

Key Technical Advantages

• Exceptional Power Handling: Designed to support the high-kilowatt requirements of FM/TV broadcasting and heavy-duty industrial RF applications.

• Superior Low PIM Performance: Engineered with non-magnetic materials and high-pressure contact surfaces to minimize signal distortion in sensitive wireless networks.

• 1-5/8″ Feeder Precision Integration: Calibrated specifically for the dimensions of 1-5/8″ corrugated cable, ensuring a seamless electrical transition with minimal VSWR.

• Gas-Tight Pressurization: Integrated O-ring grooves allow for a fully sealed, pressurizable connection, maintaining dielectric integrity and preventing oxidation in harsh tower environments.

• Unmatched Mechanical Rigidity: The standardized bolt-on flange prevents accidental loosening due to wind-induced vibration or thermal expansion, ensuring 100% uptime for mission-critical infrastructure.
