fs15 RADIAFLEX'ae functions as a distributed antenna to provide communications in tunnels, mines and largef2 building complexes and is the solution for any application in confined areas.f2 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 bef2 carried along the cable length.f2 RADIAFLEX'ae is used for both one-way and two-way communication systems and because of its broadbandf2 capability, a single radiating cable can handle multiplef2 communication systems simultaneously.f2 This RADIAFLEX'ae radiating cable utilize a low-loss cellular polyethylene foam dielectric and a smoothf2 copper outer conductor which offers a superior electrical performance together with good bending properties.f2

  • 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 radial (below 330 MHz) or parallel (above 330 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 +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.
  • 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.
