RFS-RCF12-50JFN 低煙無鹵漏波電纜 1/2" RADIAFLEX® RCF Cable

Product Description

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 from 30 MHz to 6000 MHz
Physical properties similar to the CELLFLEX® cable family of type LCF
Robust cable
Low bending radii
Main applications: in-building, vehicles, mines
Meets MSHA requirements for US mining applications

Standard conditions

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%.

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