1/2" CELLFLEX® Superflexible Foam-Dielectric Coaxial Cable

Rev : C | Rev date : 15 Nov 2025

CELLFLEX® 1/2"" superflexible cable; flame retardant/ halogen free jacket CPR rated

Feature / Benefits

  • Low Attenuation
    The low attenuation of CELLFLEX® coaxial cable results in highly efficient signal transferin 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.
