The working principle of a coaxial cable is based on electromagnetic field confinement and guided wave transmission. When the inner conductor carries a signal, the dielectric insulation keeps the electric field contained, minimizing leakage. The outer conductor acts as a shield and return path, reducing external EMI and protecting signal integrity. RG cable types (e.g., RG58, RG59, RG6, RG174) use this coaxial structure to deliver stable performance in demanding RF, video, and broadband applications.

RG58 RF cable is composed of solid bare copper, foamed polyethylene, tinned copper wire braided, and PVC sheath, with an impedance of 50 Ω and ≤ Electrical characteristics such as 6GHz operating frequency, suitable for connecting various electronic devices. RG58 cable occupies a place in the field of electronic communication due to its unique material composition, excellent electrical characteristics, good mechanical and environmental adaptability, and clear attenuation characteristics.
