1-5/8" CELLFLEX® Premium Attenuation Low-Loss Foam-Dielectric Coaxial Cable

Rev : I | Rev date : 15 Nov 2025

CELLFLEX®1-5/8" premium attenuation low loss flexible cable

Feature / Benefits

  • Ultra Low Attenuation
    The further reduced attenuation of CELLFLEX® premium attenuation 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.
  • Meets/Exceeds:   IEC 60754-1, -2; IEC 60332-1-1; IEC 61034-1, -2; IEC 60332-3-24; EN50575
