RE60-JFN
RADIAFLEX® Elliptical Waveguide, RE-series

Rev : D | Rev date : 15 Nov 2025
  • RADIAFLEX® series 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 waveguide can handle multiple communication systems simultaneously.
  • This RADIAFLEX® radiating waveguide is constructed of longitudinally continuous seam welded, highly conductive copper tube, corrugated and precision formed into an elliptical cross section. It is manufactured in continuous lengths using a special seam welding process developed by the RFS organization. The product offers a superior electrical performance together with good bending properties.

Feature / Benefits

  • Coupling loss as well as longitudinal attenuation of RADIAFLEX® elliptical waveguides is measured by the free space method according to IEC 61196-4.
  • Coupling loss values are measured with a log-periodic antenna with gain of approx. 6 dBi in specified frequency range.
  • The coupling loss values are average values of the three spatial orientations (radial, parallel and orthogonal) of log-periodic antenna.
  • Coupling loss values are given with a tolerance of ±6 dB and longitudinal loss values with a tolerance of ±5%.
  • As with any radiating element, the performance in building or tunnel enviorments may deviate from figures based on free space mthod.
