FEATURES & BENEFITS
  • 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.
  • Broadband from 30 MHz to 1000 MHz
  • Optimized for high frequencies and digital transmission
  • For tunnel applications
  • Low coupling loss variations
  • Euroclass acc. to EN 50575: Dca s1b d2 a1
