Coaxial cable

This RG58-type coaxial cable is designed for 50 Ω radio frequency applications such as transmitting equipment, test setups, and antenna connections. The cable has an impedance of 50 Ω, a shielding effectiveness of approximately 40 dB, and features double shielding. Its thin and flexible construction (5 mm outer diameter) makes the cable suitable for installations with limited space and applications where flexible handling is required. The cable complies with CPR (EN 50575) fire class Eca and is suitable for fixed indoor installation. Supplied as a cable reel, 100 meters in length.

Explanation of terms used Impedance (50 Ω) Characteristic resistance of the coaxial system; 50 Ω is used in RF and transmission applications to optimize power transfer and minimize reflections. Shielding (approx. 40 dB) Provides basic protection against external interference in standard RF environments. CPR / EN 50575 European fire classification for cables in fixed installations. Fire class Eca meets the minimum fire safety requirements within buildings. CCS Steel core with copper coating; used at high frequencies where conduction primarily occurs at the surface. General explanation of coaxial cable A coaxial cable consists of a central inner conductor, a dielectric, one or more shielding layers, and a protective outer sheath. This construction ensures controlled signal transmission with minimal interference and low attenuation. RG58-type is a 50 Ω cable with an outer diameter of approximately 5 mm for RF and measurement applications. RG59-type is a 75 Ω cable for basic television and CCTV installations. RG6-type is a 75 Ω cable with an outer diameter of approximately 7 mm for digital DVB and satellite applications. COAX9 is a 75 Ω cable with a high shielding value (usually 100 dB, Class A) for installations with increased electromagnetic interference. Ask a product question
