RCF158-50JFLA
1-5/8" RADIAFLEX® RCF 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 corrugated copper outer conductor which offers a combination of remarkable flexibility, high strength and excellent electrical performance.

FEATURES / BENEFITS

Broadband radiating cable supporting all wireless application between 30 MHz to 2750 MHz
Ideally suited for application that require low bending radii
Robust radiating cable operational under all enviromental conditions as e.g. harsh tunnels or mines

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 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.
As with any radiating cable, the performance in building or tunnel environments may deviate from figures based on free space method.
