product description
7/8" RADIAFLEX® Radiating Cable
RFS Item Number: RAY78-50JFLA
>>> Prices and availability on request!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
