摘要

An air dielectric coaxial cable in which variations in phase characteristics due to variations in ambient temperature are minimized. An insulator is formed by welding a spiral rib which is in contact along one edge thereof with the outer wall of the inner conductor to an outer pipe of the same material. The outer conductor is provided in close contact with the outer wall of the insulating pipe. The space factor of the insulator is set between predetermined limits in accordance with a disclosed technique.
