CATV Broadband Coaxial Cables-1 75-Ohm, Gas-Injected PE Broadband Coaxial Cables (RG59, RG6, RGQUAD, RG11).

Coaxial cables, or coax, is an with an inner conductor surrounded by a tubular insulating layer typically of a flexible material with a high, all of which are surrounded by a conductive layer (typically of fine woven wire for flexibility, or of a thin metallic foil), and finally covered with a thin insulating layer on the outside. The term comes from the inner conductor and the outer shield sharing the same geometric axis. Coaxial cable is used as a for signals, in applications such as connecting and with their antennas, computer network connections, and distributing cable television signals. One advantage of coax over other types of transmission line is that in an ideal coaxial cable the carrying the signal exists only in the space between the inner and outer . This allows coaxial cable runs to be installed next to metal objects such as gutters without the power losses that occur in other transmission lines, and provides protection of the signal from external.

Coaxial cable should not be confused with other used for carrying lower frequency signals such as. Shielded cable is similar in that it consists of a central wire or wires surrounded by a tubular shield conductor, but it is not constructed with the precise conductor spacing needed to function efficiently as a radio frequency.
