Radio Frequency Systems - Coaxial Cable Connectors for Mobile and Wireless Transmission

Radio Frequency Systems (RFS) is a global designer and manufacturer of cable and antenna systems, providing total-package solutions for wireless infrastructure.

RFS offers a complete line of transmission line systems, air and foam dielectric coaxial cables, factory-made jumper assemblies, connectors, as well as a large variety of installation accessories.

These products include the following:

• CELLFLEX® foam dielectric coaxial cable - for mobile and wireless infrastructure applications
• HELIFLEX® air dielectric coaxial cable - for communications, broadcast and other high-power systems
• RADIAFLEX® radiating coaxial cables - for tunnels and in-building wireless distributed communications systems
• FLEXWELL® elliptical waveguides - flexible transmission lines for microwave antenna systems

RFS connectors and transmission line products are used by major telecommunication service providers, network equipment manufacturers, broadcasters and government agencies worldwide.

CELLFLEX® TRANSMISSION LINE COAXIAL CABLE

RFS has developed CELLFLEX®, the broadest range of low-attenuation transmission line cables for high performance applications within the telecommunications sector.

These cables are ideally suited for the demands of 3G networks, system expansion overlays and extra-long transmission line runs. A decrease in attenuation has been achieved for all major cable sizes - 7/8in, 1-1/4in, 1-5/8in and 2-1/4in.

Constructed of a closed-cell polyethylene dielectric and welded-seam solid copper conductors, these cables have passed rigorous testing and meet exacting performance specifications.

They are available in standard polyethylene or flame-retardant polyethylene jacket materials, and with premium VSWR levels in several telecommunication bands.

HELIFLEX® COAXIAL CABLE

HELIFLEX® coaxial cable's solid inner and outer conductors virtually eliminate intermodulation, and provide highly efficient signal transfer in RF systems. The solid outer conductor of HELIFLEX® coaxial cable creates a continuous RFI / EMI shield that minimizes system interference.

Due to their low attenuation, outstanding heat transfer properties and temperature-stabilized dielectric materials, HELIFLEX® cable provides safe long-term operating life at high transmit power levels.

Typical areas of application are: feedlines for broadcast and terrestrial microwave antennas, wireless cellular, PCS and ESMR base stations, cabling of antenna arrays, and radio equipment interconnects.

RADIAFLEX® RADIATING CABLE

RADIAFLEX® functions as a distributed antenna to provide communications in confined areas and locations such as tunnels, mines and large building complexes.

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.

RADIAFLEX® radiating cables utilise 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.

FLEXWELL® ELLIPTICAL WAVEGUIDE

The FLEXWELL® elliptical waveguide is constructed of continuous seam-welded, highly conductive copper tube, corrugated and precision-formed into an elliptical cross section.

This corrugated design achieves high transverse stability, flexibility and crush strength for superior handling and forming at an installation. FLEXWELL® waveguide enables a continuous length of waveguide to be directly connected from a tower-mounted antenna to the equipment building, eliminating flange joint discontinuities and the use of bends, twists and flex sections associated with a rigid rectangular waveguide systems.

Because of its flexibility, FLEXWELL elliptical waveguide can be easily transported to an installation site in coils or on reels and then uncoiled as required during installation.
