Product Overview
The model of RF coaxial cable RG58 is RG58.The design of coaxial cable is based on the "coaxial line" principle, where the inner and outer conductors lie on the same axis, with an insulating dielectric between them. This structure confines the electromagnetic field to the inner and outer conductors. According to Maxwell's equations, this effectively reduces electromagnetic radiation and external interference, achieving low-loss, high-efficiency signal transmission. Its core performance parameters include characteristic impedance, propagation velocity, and attenuation constant. Characteristic impedance is determined by the radius of the inner and outer conductors, as well as the dielectric constant of the insulating dielectric. The commonly used impedance standards of 50Ω and 75Ω are based on optimizing power transmission efficiency and minimizing signal reflections in different application scenarios.
