Coaxial 7/8″ Super Flexible Cable

Description

7/8″ Cable Super Flexible is a type of RF coaxial cable which is used to transfer RF signals from one point to another which allows for precise bending and handling when needed in tight spaces. Typically, 7/8″ Cable Super Flexible is used as as Main feeder for mobile communication base stations, In-building distribution system and antenna feed lines of various wireless communication system, jumper cables to connect to an antenna of transmission equipment. It incorporates high foaming polyethylene insulation technology to minimize signal loss and have excellent electric features such as low damping and reflection coefficient.
