ABSTRACT:
A high-precision foamed coaxial cable includes an internal conductor constructed by stranding conductors, an insulator constructed by winding a porous tape around an outer circumference of the internal conductor, and an external conductor constructed by braiding a plurality of thin conductor wires around an outer circumference of the insulator. The insulator is formed to have a right circle external shape, an outside diameter of the insulator is formed smaller at a reduction rate of 3 to 5% than the outside diameter, immediately after the winding, of the insulator. The external conductor is formed to have a right circle external shape, an outside diameter of the external conductor is formed smaller at a reduction rate of 2 to 4% than the outside diameter, immediately after the braiding, of the external conductor, and precision of its characteristic impedance is set at ±1 Ω.
