EIA FLANGE for 1/2″ FEEDER Cable

Description

The EIA (Electronic Industries Alliance) Flange series is the industry standard for high-power, low-loss RF transmissions. This variant is specifically designed for 1/2″ Feeder (Corrugated) cable, providing a rigid and extremely stable connection point between flexible feeder lines and high-power equipment like transmitters or combiners. Unlike threaded connectors, the EIA flange utilizes a bolt-circle mounting system with a high-pressure O-ring seal, ensuring a gas-tight, pressurized, or non-pressurized connection that can withstand extreme environmental conditions.

Maintaining a strict 50-Ohm impedance, this connector is optimized for Low PIM (Passive Intermodulation) performance, which is critical for modern multi-carrier cellular and broadcast systems. It features a robust mechanical clamp or solder termination for the 1/2″ cable’s corrugated outer conductor and a high-conductivity inner contact system. Manufactured with a tri-metal (white bronze) or silver-plated brass body and premium insulation, it delivers exceptional shielding effectiveness and minimizes signal loss even at high power levels across the VHF, UHF, and microwave spectrum.

Key Technical Advantages

• Standardized High-Power Interface: The EIA flange design (typically 7/8″ EIA for 1/2″ cable transitions) allows for a rigid, secure connection to high-wattage transmitters and antenna systems.

• Low PIM Optimization: Specifically engineered to minimize passive intermodulation, ensuring clear signal transmission in sensitive multi-band wireless networks.

• 1/2″ Feeder Precision Fit: Calibrated for the specific geometry of 1/2″ corrugated coaxial cable, ensuring a seamless mechanical and electrical transition for maximum power transfer.

• Weatherproof & Pressurizable: Features an integrated O-ring gasket system that allows the connection to be pressurized with dry air or nitrogen to prevent moisture ingress in outdoor tower installations.

• Superior Mechanical Stability: The four-bolt (or six-bolt) flange pattern provides unmatched resistance to vibration, wind load, and cable torque compared to standard threaded interfaces.

Key Features

• Interface Type: EIA Flange (compatible with standardized bolt patterns).

• Termination Method: Mechanical Clamp or Solder-inner for 1/2″ corrugated cable.

• Cable Compatibility: Optimized for 1/2″ Feeder, Superflex, and standard corrugated coaxial cables.

• Premium Construction: Features a silver or tri-metal plated brass body and a high-performance dielectric for thermal stability.

• Industrial Application: Ideal for FM/TV broadcast transmitters, cellular base station main feeds, radar systems, and satellite earth stations.
