Four stages of skin effect in a coax showing the effect on inductance.Coaxial cables transmit signals through the center wire. To ensure a quality signal travels the length of the cable a metal shield is needed. Both components receive a current simultaneously, generating a magnetic field. This allows the signal to remain intact and not bleed out like it would without the shield.Thus, 50 Ohm Coaxial Cable was selected as the ideal compromise; offering high power handling AND low attenuation characteristics.
