4" Air-Dielectric Coaxial Cable, 50 ohm, Plenum Rated, Black Jacket

Rev : C | Rev date : 11 Mar 2024

4" low loss air dielectric cable, plenum rated, UV resistant black PVC Jacket, applicable to both outdoor and indoor applications.

RFS Technologies' air dielectric cables are air filled coaxial cables which consist of an inner conductor and an outer conductor. A dielectric helix is used to center the inner conductor to the outer conductor. Air dielectric cables have low attenuation and high power rating which make them perfect choice of high RF power transmission lines, such as in FM, TV and radar systems and networks. Air cables also have better flexibility and crush resistance than other solutions such as rigid lines.

FEATURES / BENEFITS

  • Low Attenuation
    The low attenuation of this coaxial cable results in highly efficient signal transfer in your RF system.
  • Complete Shielding
    The solid outer conductor of this coaxial cable creates a continuous RFI/EMI shield that minimizes system interference.
  • Low VSWR
    Standard and low VSWR versions of this coaxial cables contribute to low system noise.
  • Outstanding Intermodulation Performance
    Coaxial cable's solid inner and outer conductors virtually eliminate intermods. Intermodulation performance is also guaranteed by the state-of-the-art manufacturing process at the factory.
  • High Power Rating
    Low attenuation, outstanding heat transfer properties and temperature stabilized dielectric materials enable this cable to provide long operating life at high transmit power levels.
  • Wide Range of Application
    Air cables are good choices for telecom, broadcasting, radar and HF defense applications.
  • Plenum Rated
    PVC jacket prevents fire from spreading, enables JPLB cables to meet and exceed all applicable plenum standards of flame travel and smoke.
  • Reinforced Jacket to Sustain Outdoor Applications
    Spcial additives in the jacketing compound improve the outdoor durability of the PVC jacket by minimizing the surface degradation caused by sunlight and other UV sources.
