A coaxial line is an essential component in transmitting high-frequency radio signals. This type of transmission line consists of an inner conductor surrounded by an insulating layer and an outer conductor that serves as a shield. However, there are several other terms that may be used interchangeably with coaxial line, including coaxial cable, coax cable, or simply coax. Additionally, these cables may come in varying sizes, such as RG-6 or RG-11, which refer to the diameter of the cable and its impedance. Regardless of the specific terminology used, the coaxial line remains a critical element in modern communication and technology, facilitating the transfer of data and signals over long distances with minimal interference.
