The 7/8' EIA flange connector for 1-5/8' foam feeder cable is a specialized RF adapter that allows a larger 1-5/8 inch foam dielectric coaxial cable to be terminated with a smaller 7/8 inch EIA standard flange interface. This type of connector is used in systems where high-power cables need to interface with equipment or components designed for 7/8 inch flanges. It provides a reliable mechanical and electrical connection, ensuring low signal loss and high power handling, commonly used in base stations, RF combiners, and broadcast infrastructure.
