Coaxial cables are widely used for transmitting high-frequency signals in a variety of applications, including telecommunications, internet services, and television broadcasting. They are commonly found in cable TV systems, where they carry video and audio signals from the provider to the home. In networking, coaxial cables are used for connecting devices in legacy Ethernet networks or in modern broadband connections. Additionally, they are utilized in surveillance systems to transmit video from security cameras to monitors or recording devices. Coaxial cables are also used in satellite communication, providing a reliable medium for transmitting data between satellites and ground stations, due to their ability to minimize signal loss and electromagnetic interference.
