CELLFLEX® 1/2" SCF12-50J - 250m

Product.Nr.: 804003

product description

1/2" CELLFLEX® Superflexible Coaxial Cable

RFS Item Number: SCF12-50J

  • 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, OEM jumpers, main feed transitions to equipment, GPS lines, intended for outdoor usage.
  • Euroclass acc. to EN 50575: Fca
