The main feature of coaxial cable⚡️

A coaxial cable has a central copper conductor surrounded by a dielectric, topped by a copper shielding braid, all within a protective sheath. The signal flows through the central conductor, while the shielding protects against interference and serves as the return conductor. Characteristic impedance is typically 50 or 75 ohms—for instrumentation and television, respectively. At higher frequencies, losses increase, so above gigahertz, it is replaced by waveguides.
