Coaxial Cables Italian Luccables is a society that supplies Coaxial Cables Italian;
Coaxial cable is an electrical cable consisting of a round conducting wire, surrounded by an insulating spacer, surrounded by a cylindrical
conducting sheath, usually surrounded by a final insulating layer. It is used as a high-frequency transmission line to carry a
high-frequency or broadband signal. Sometimes DC power (called bias) is added to the signal to supply the equipment at the other end,
as in direct broadcast satellite receivers. Because the electromagnetic field carrying the signal exists (ideally) only in the space
between the inner and outer conductors, it cannot interfere with or suffer interference from external electromagnetic fields.
Coaxial cables may be rigid or flexible. Rigid types have a solid sheath, while flexible types have a braided sheath,
both usually of thin copper wire. The inner insulator, also called the dielectric, has a significant effect on the cable's
properties, such as its characteristic impedance and its attenuation. The dielectric may be solid or perforated with air spaces.
Connections to the ends of coaxial cables are usually made with RF connectors.
