Overview

Cablewave-RFS HCA300-50J 3" HELIFLEX® Air-Dielectric Coaxial Cable

  • Low Attenuation: The low attenuation of HELIFLEX® coaxial cable results in highly efficient signal transfer in your RF system.
  • Complete Shielding: The solid outer conductor of HELIFLEX® coaxial cable creates a continuous RFI/EMI shield that minimizes system interference.
  • Low VSWR: Special low VSWR versions of HELIFLEX® coaxial cables contribute to low system noise.
  • Outstanding Intermodulation Performance: HELIFLEX® 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, HELIFLEX® 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
