Coaxial cables or COAX cables are the ideal solution for all applications requiring high speed data and video, flexibility, protection from extreme environment and high and low temperature resistance. Where you need a signal with minimum distortion and attenuation or no interferences, coaxial cables play a pivotal part. In fact, thanks to their twin conductor construction nature, they are able to ward off many issues produced by bifilary wires.
Coaxial cables consist of two copper or aluminium coaxially oriented conductors surrounded by a tubular insulating layer, enclosed by a conducting shield. The quality of coaxial cables affects the signal interference; higher quality ensures a minimum signal interference. Moreover, also the density of the shielding affects the quality of the COAX. The result is that high quality materials and manufacturing process are essential to manufacture a reliable coaxial cable.
Generally, coaxial cables end with connectors that are usually manufactured with high conductivity metals. There are many different kinds of coaxial cables, which are generally defined by electrical capabilities, outer diameter or materials. However, most coaxial cables are manufactured in line with RF industry standards, the American norm MIL-DTL-17 and the French norm NF-C-93550.
An example is represented by RG cables, where the copper and aluminium copper clad wire quality, as well as the foaming extrusion, are part of the efficiency of signal.
Coaxial cables are also used for vehicle antenna connections and related RF signal paths. When selecting a cable for an automotive antenna system, buyers should consider impedance, attenuation, cable dimensions, connector compatibility, installation space, and the requirements of the existing equipment.
Xingfa lists its 17VATC coaxial cable for vehicle antenna applications. The current 17VATC specification uses a 75-ohm construction with a 17 AWG conductor and is designed as part of Xingfa’s VATC coaxial cable range.
Wireless communication systems, base stations and antenna installations rely on coaxial cables to transmit RF signals between radio equipment and antennas. Cable selection should consider the required impedance, operating frequency, transmission distance, allowable attenuation, shielding performance, connector compatibility and installation environment.
For applications requiring a larger 75-ohm foam coaxial construction, Xingfa's 8D-FB coaxial cable uses a 2.80 ± 0.05 mm BC/CCS center conductor, foam-PE dielectric, aluminum-foil and tinned-copper braid shielding, and an approximately 11.10 ± 0.05 mm overall diameter. Xingfa currently specifies 8D-FB for RF transmission in wireless communication, broadcasting, base stations and antenna applications.
Buyers comparing different FB-series cables should evaluate the actual system specification and published attenuation at the required operating frequency rather than selecting a cable based only on model number or diameter.
Although the solutions for a high quality coaxial cable manufacturing look like straightforward, the design of these lines requires expertise and a deep understanding of the final product. Here, we do not see our intervention as a mere product supplier. Our solid expertise in the field as manufacturer, designer and supplier of these remanufacturing solutions, gives us an holistic understanding and all the know how to optimize the solution based on customer needs and specific industry requirements from the drawing (single wire & multi-wire) to the extrusion (insulation & sheathing), passing through the wire assembling (bunching).
