RLKD12-50JFLA
1/2" RADIAFLEX® RLKD 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 smooth copper outer conductor which offers a superior electrical performance together with good bending properties.

FEATURES / BENEFITS

  • Broadband from 800 MHz to 6000 MHz
  • For applications in buildings

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 measured with a orthogonal (below 1500 MHz) or parallel (above1500 MHz) orientated dipole antenna.
  • The coupling loss values given in brackets are average values of all three spatial orientations (radial, parallel and orthogonal) of dipole antenna.
  • Coupling loss values are given with a tolerance of +5 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.
  • In case of a conflict of operational and stop band, please contact RFS for further assistance.
  • As with any radiating cable, the performance in building or tunnel environments may deviate from figures based on free space method.
