Coaxial cables are copper cables designed with a metal shield and other specialised components to prevent signal interference. They are widely used by cable TV providers to connect their satellite antenna facilities to residential and commercial buildings.
The cables are also used in other applications, such as in computer networks, security systems, and in the telecommunications industry for transmitting high-frequency signals. Due to their ability to prevent interference, coaxial cables are favoured for applications that require high-speed data transmission and reliable signal quality.
