EIA Flange Connector

EIA Flange Connectors are high-power RF coaxial connectors designed for low-loss signal transmission in broadcasting, telecom, RF, microwave, and high-power communication systems. These connectors provide excellent impedance matching, high power handling capability, low VSWR, and reliable RF connectivity for large coaxial transmission lines and rigid line systems.

At SRFS Teleinfra, we manufacture premium-quality EIA Flange Connectors using precision-machined components and high-grade conductive materials to ensure stable electrical performance, excellent shielding effectiveness, and long operational durability. Our EIA flange connectors are widely used in FM broadcasting systems, TV transmitters, telecom towers, microwave networks, and high-power RF infrastructure systems.

EIA Flange connectors are specially designed for rigid coaxial transmission line systems where high-power RF transmission and secure mechanical connectivity are critical. These connectors are widely preferred in industrial communication systems because of their low insertion loss and strong mechanical stability.
