Coaxial cables, often referred to as RF (Radio Frequency) cables, are designed to transmit radio signals with minimal interference from external electromagnetic fields. These cables are constructed with a central conductor surrounded by an insulating layer, over which a metallic shield is placed, and then covered by an outer insulating sheath. The main function of coaxial cables is to carry high-frequency electrical signals with low signal loss, making them ideal for applications such as television broadcasting, internet connections, and radio frequency transmissions.
The primary uses of coaxial cables include connecting radio transmitters and receivers with their antennas, internet connections, and distributing cable television signals. One of their key characteristics is the ability to guard against signal interference, which helps in maintaining the integrity of the data transmitted over long distances. Some well-known manufacturers of coaxial cables include Belden, Amphenol, and L-com.
