    Features/Benefits

    • Low Attenuation
       The low attenuation of CELLFLEX® coaxial cable results in highly efficient signal transfer
       in your RF system.
    　

    • 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.
