Coaxial cable
Coaxial cable, or coax (pronounced as "co-ax," not as the verb "to coax"), is a type of cable widely used as a feed line in radio systems, including in amateur radio. It consists of an inner conductor surrounded by a conducting shield, with the two separated by an insulating material called the dielectric; virtually all coaxial cables used in amateur radio also have a protective outer sheath or jacket, although this is not technically required for the cable to function. The term "coaxial" refers to the inner conductor and the outer shield sharing a geometric axis.
Coaxial cables are connected using special connectors designed for this type of cable. Coaxial connectors are designed to maintain a coaxial form across the connection and have the same impedance as the attached cable.
