To obtain better overall performance characteristics and reliability, Micro-Coax developed a wide range of semi-rigid cable solutions and is now the world’s largest manufacturer of semi-rigid cables.

Micro-Coax Semi-Rigid Coaxial Cable offers more options than any other cable manufacturer. Cables with a large range of impedances, diameters, materials, and finishes are available from stock. For overnight delivery, over 40 of our most popular cable sizes and jacket finishes are now available on our new cable web store.

Semi-rigid cable comes as close as possible to the ideal coaxial cable and should be the first choice of any RF/Microwave Engineer.

Semi-rigid cable designs optimize dielectric properties and shielding quality. Micro-Coax semi-rigid cable is still the best pure microwave transmission medium available in the world. The solid tubular outer conductor yields 100% RF shielding and enables the dielectric and center conductor to remain precisely spaced. This results in optimum impedance control as well as the lowest possible insertion loss and weight to size ratios.

Semi-rigid cables are also inexpensive to purchase when compared to many other coaxial cable alternatives. The primary considerations for using semi-rigid are the availability of bend tooling, the difficulty in routing and the need to reform the cable.
