Rev : A | Rev date : 08 Jan 2026

CELLFLEX® Lite 7/8" low loss cable

Features / 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.
