同轴电缆（射频）

Coaxial cable products consist of two or more conductors of circular cross section, the center points of which are coincident in the finished product. They are differentiated from shielded cables having one internal conductor by the degree of care used in manufacturing; products considered coaxial cables are manufactured with greater attention paid to maintaining consistent conductor geometries, insulation thickness, and insulation dielectric properties along the length of the cable, in order to minimize discontinuities in cable characteristics along its length that would adversely affect its utility for carrying high frequency signals.
