A type of cable with a central wire surrounded by insulation which separates it from a conductive mesh sleeve, the whole being then covered a protective insulating sleeve and generally used for conveying television pictures.
Any cable that has a conductor and shield sharing the same axis. Also known as RG59.
A cable comprising a central wire surrounded by a second tubular screening of fine wire. Associated with IBM for linking terminals and other devices needing high-speed links, coax is used in Ethernet. It is difficult to add or remove devices from a coaxial LAN as the cable is unwieldy and thick so is being superseded by UTP.
A high-capacity cable used in communications and networking. It contains an insulated solid wire surrounded by a solid or braided metallic shield.
Electrical cable where the inner core is surrounded by an outer metal core separated by insulation. Usually rated at 8 ohms.
Cable of the type used to connect radio transmitters and receivers to aerials. It is normally a core of copper wire (either solid or stranded) which is surrounded by, but insulated from an outer screen, again of copper wire which is usually stranded into a web. This is further insulated from the elements by some non-conductive material. Co-ax is measured by its Impedance. The two commonest impedances are 50 ohms per metre and 75 ohms per metre. Transceivers use 50 ohm co-ax, while 75 ohm co-ax is used for televisions.
Cable with a metal core and insulated sheath along which information is conveyed in the form of electrical current.
This refers to cable that has a central conductor, surrounded by a shield sharing the same axis. The shield can be made from a variety of materials including braided copper, or lapped foil. There are various standards fro specific types of co-axial cable. The cable used for normal CCTV installations is called RG59.
