A coaxial cable, also known as a coax cable or simply a coax, is a type of cable used in telecommunications and computer networking applications to transmit signals with high bandwidth. There are several synonyms for coax cable one of which is "RF cable" - an abbreviation of radio frequency cable, which refers to the specific type of electromagnetic wave that the cable carries. Another synonym is "shielded cable" which describes the cable's metallic shielding layer that reduces interference from other electronic devices. Finally, the term "RG cable" is commonly used for coaxial cables that meet certain military standards, such as RG-6, RG-58, or RG-174, which specify the cable's diameter, shielding, and impedance characteristics.
