The invention relates to a low-loss stationary-phase coaxial radio-frequency cable and a manufacturing process thereof. A plurality of layers of microporous polytetrafluoroethylene film insulating layers are wrapped outside the core of a silver-plated copper alloy wire; a silver-plated copper bandlet inner shield is wrapped outside the plurality of microporous polytetrafluoroethylene film insulating layers; a layer of silver-plated copper wire outer conductor is woven outside the silver-plated copper bandlet inner shield; and a layer of fluorinated ethylene propylene jacket is wrapped outside the silver-plated copper wire outer conductor by pressing. The process comprises the following steps of: 1, plating silver on a copper alloy wire in-core conductor; 2, wrapping the microporous polytetrafluoroethylene film insulating layers; 3, wrapping the silver-plated copper bandlet inner shield; 4, weaving the silver-plated copper wire outer conductor; and 5, wrapping the fluorinated ethylene propylene jacket by pressing. The process has the characteristics of reducing the dielectric constant of an insulating medium, reducing the attenuation of the cable and guaranteeing the high shielding efficiency of the cable.
