LCF78-50JA-ECO
7/8" CELLFLEX® ECO Low-Loss Foam-Dielectric Coaxial Cable

Rev : A | Rev date : 15 Nov 2025

The CELLFLEX® LCF78-50J-ECO cable family is a high-performance, low-loss coaxial solution designed for modern broadcast and telecom applications. It features a robust, corrugated copper outer conductor and a foam PE dielectric for excellent electrical performance. The ECO version uses a jacket made with partially recycled PE, supporting sustainability initiatives without compromising quality. Its outstanding attenuation characteristics and mechanical flexibility make it ideal for feeder and jumper cable installations. The cable is engineered for long service life, maintaining stable performance even under harsh environmental conditions. Designed for use with ECO connectors, but also fully compatible with E01 and C03 connectors when using the appropriate preparation tool.

Feature / Benefits

  • Ultra Low Attenuation

The reduced attenuation of CELLFLEX® coaxial cable results in extremly efficient signal transfer in your RF system, especially at high frequencies. 

  • Complete Shielding

The solid outer conductor of CELLFLEX® coaxial cable creates a continuous RFI/EMI shield that minimizes system interference. 

  • Low VSWR

Special low VSWR versions of CELLFLEX® coaxial cables contribute to low system noise. 

  • Outstanding Intermodulation Performance

CELLFLEX® coaxial cable's solid inner and outer conductors virtually eliminate intermods. Intermodulation performance is also confirmed with state-of-the-art equipment at the RFS factory. 

  • High Power Rating

Due to their low attenuation, outstanding heat transfer properties and temperature stabilized dielectric materials, CELLFLEX® cable provides safe long term operating life at high transmit power levels. 

  • Wide Range of Application

Typical areas of application are: feedlines for broadcast and terrestrial microwave antennas, wireless cellular, PCS and ESMR base stations, cabling of antenna arrays, and radio equipment interconnects

  • Sustainable Performance:
