RCF158-50JFLA
1-5/8" RADIAFLEX® RCF Cable, A-series

  • RADIAFLEX® functions as a distributed antenna to provide communications in tunnels, mines and large building complexes and is the solution for any application in confined areas.
  • Slots in the copper outer conductor allow a controlled portion of the internal RF energy to be radiated into the surrounding environment. Conversely, a signal transmitted near the cable will couple into the slots and be carried along the cable length.
  • RADIAFLEX® is used for both one-way and two-way communication systems and because of its broadband capability, a single radiating cable can handle multiple communication systems simultaneously.
  • This RADIAFLEX® radiating cable utilize a low-loss cellular polyethylene foam dielectric and a corrugated copper outer conductor which offers a combination of remarkable flexibility, high strength and excellent electrical performance.
  • FEATURES / BENEFITS

    • Broadband radiating cable supporting all wireless application between 30 MHz to 2750 MHz
    • Ideally suited for application that require low bending radii
    • Robust radiating cable operational under all enviromental conditions as e.g. harsh tunnels or mines

    Notes

    • Coupling loss as well as longitudinal attenuation of RADIAFLEX® cables are measured by the free space method according to IEC 61196-4.
    • Coupling loss values are average values of all three spatial orientations (radial, parallel and orthogonal) of dipole antenna.
    • Coupling loss values are given with a tolerance of +10 dB and longitudinal loss values with a tolerance of +5%. Note: Measured values below nominal are better. They are not limited by any tolerance-range.
    • As with any radiating cable, the performance in building or tunnel environments may deviate from figures based on free space method.
