RFS CELLFLEX LCF158-50JA 1-5/8" EIA Flange Coax RF Satcom Cable 23 ft

RFS CELLFLEX LCF158-50JA 1-5/8" EIA Flange Coax RF Satcom Cable 23 ft

The RFS CELLFLEX LCF158-50JA is a 1-5/8" diameter 50-ohm flexible coaxial transmission cable designed for high-power RF applications in satellite communications and broadcast earth station systems. CELLFLEX is RFS's line of corrugated-jacket flexible coaxial cable, offering the low-loss characteristics of a rigid hard-line in a form factor that can be routed around obstacles and through conduit. This example is 23 feet long and terminated at both ends with 1-5/8" EIA standard flange connectors.

Applications

The RFS CELLFLEX LCF158-50JA is used as a transmission line between high-power RF amplifiers or transmitters and the antenna feed system in satellite communications earth stations, broadcast uplink facilities, and military/government satcom ground terminals. The 1-5/8" EIA flange interface is an industry-standard connection found on high-power amplifiers (HPAs), waveguide runs, antenna feed networks, and diplexers operating in frequency bands from L-band through Ku-band and beyond. At this diameter, CELLFLEX cable handles kilowatt-level transmit power levels while maintaining flexibility for routing through equipment rooms and antenna towers — an advantage over rigid hard-line coax in installations where bends and routing changes are required. This type of cable has been a staple of professional satcom earth station infrastructure since the 1980s and remains in active use today in commercial, government, and military ground station installations. It is also used in broadcast RF plants and high-power radar feed systems where both low loss and routing flexibility are needed.
