Transmission Lines

    Coaxial cables


    CELLFLEX

    - foam-dielectric coaxial cable products are available for mobile and wireless infrastructure applications

    HELIFLEX

    - air-dielectric coaxial cable products are used in several communications, broadcast and other high power systems.

    RADIAFLEX

    - radiating cables facilitate radio communication where the usual free space propagation of electromagnetic waves is hampered, undesired or impossible: in tunnels, mines, buildings, alongside tracks or lines and in large complex like exhibition grounds or airports.

    FLEXWELL

    - air dielectric cables combine excellent flexibility with low attenuation and high power ratings and are gas tight.

    Accessories

    While a number of cable related accessories are available on the market, RFS components are of the highest quality and are designed to provide years of trouble-free service. Together with the RFS transmission line products they have been thoroughly tested and released to insure inter-operability. RFS offers all necessary tools and accessories for a complete cable system, such as:

  • Cable Hangers


  •  

     
  • Trimming Tool

    Special trimming tools make the connector attachment onto CELLFLEX® foam dielectric cables even easier. No further tools are required to prepare the cable for the connector attachment. This is due to the special design of the trimming tool, which combines all necessary functions in one compact tool.

  • High Speed Grounding Kit

    The HSE grounding kit is a pre-assembled grounding kit for low loss and flexible cables from sizes 1/4" to 1-5/8". After the installation, the grounding is resistant to all environmental influences.

    EMP Protection Devices

    Atmospheric disturbances may cause problems in antenna and cable systems and can present a severe danger to high-frequency equipment. The two most effective types of EMP protection are the spark gap and the quarter wavelength shorting stub. RFS offers devices using coaxial technology for N and 7-16 connector systems. During normal operation these devices will not influence the RF behaviour of the antenna and cable system.

  • Foam Dielectric Jumpers

    CELLFLEX® foam dielectric jumper cables provide the ideal combination of low-loss, high-strength and highest flexibility for optimum performance. Jumper cables are mainly used between main feeders and antennas or between main feeders and system equipment. Jumper cables from RFS are manufactured with flexible and superflexible cables. Standard jumpers are offered with the following cable types and connectors. o SCF14-50 J with N or 7-16 connectors o SCF38-50 J with N or 7-16 connectors o SCF12-50 J with N or 7-16 connectors o LCF12-50 J with N or 7-16 connectors The molded version is available in standard lengths of 1m, 2m, or 3m. For the assembled version the standard lengths are 3ft, 6ft, 8ft or 10ft.

    Connectors


    the connector design offers a significant installation advantage due to a one-piece item. That means, no assembly is required during installation. All connectors are available as N, EIA, 100-203, as well as 7-16 types, male or female.
  • Connector Series 7-16

    The 7-16 connector is the most rugged RF connection meeting all requirements even under severe environmental conditions.

  • Connector Series N

    The N connector is one of the most common RF connector types. N type connectors from RFS will be delivered with a non-slotted outer conductor contact sleeve and a special gasket. Due to a special design of the coupling nut (without spring ring) N connectors can be tightened with increased torque. This increases the contact pressure.

  • Connector Series EIA

    To join two cables with EIA connectors, two identical socket connectors are installed on one end of the cables to be joined, and a coupling element is required to make the connection of the center conductor. The coupling element must be ordered separately. Connectors are available in sizes matching the nominal cable size. EIA connectors provide optimal power handling for the complete transmission line system.


  •  

     
  • Connectors Series 100-230

    This special design is exclusive for 8" and 9" diameter HELIFLEX® cables and are optimized for high-power, low-frequency applications. They are designed to be welded onto the inner and outer conductors to provide years of trouble-free operation. The coupling interface is comparable to EIA-type flanges and uses coupling elements for inter-connection between identical connectors.

  • New RAPID FIT™ Connectors

    RAPID FIT™ connectors use a simple technique for easy installation. RAPID FIT™ connectors are a single-piece design that quickly terminate to the cable. After cutting the jacket to the required length the connector is screwed onto the cable and tightened. It is not necessary to flare the outer conductor, so a flanging tool is not required for RAPID FIT™ connectors.

    Sealing


    There are several solutions for the water-proofing of CELLFLEX® and HELIFLEX® connectors. Instead of relying on additional weatherproofing kits only, our connectors are perfectly sealed against environmental threats by using specially designed O-rings or gasket seals, or by injecting Plast 2000 between the cable and connector interface. Types of sealing: - Sealing with Plast 2000 - Sealing with heat shrinking tube - Sealing with cold shrinking tube - Sealing with O-ring
