Semi-Rigid Coaxial Cable

Semi-rigid cable comes as close as possible to the ideal coaxial cable and should be the first choice by any RF/microwave engineer. We offer semi-rigid coaxial cable options with a large range of impedances, diameters, materials, and finishes. Many are available for immediate delivery.


50 Ω Copper These cables feature low attenuation and VSWR. With numerous connector options available off-the-shelf, this family of cables is one of the most versatile available today. They provide total shielding for the elimination of signal loss and noise.

  • Diameters from 0.013" to 0.390"
  • Available with silver-plated and tin-plated outer conductor

50 Ω Aluminum Our 50 Ω aluminum semi-rigid cables offer easier bending and significant weight reduction.

  • Available in both standard and low-loss versions
  • Available with a tin-plated outer conductor

Low-Loss 50 Ω Copper & Low-Loss 50 Ω Aluminum Low-loss semi-rigid cables provide lower attenuation, better phase stability with temperature, and a higher operating temperature compared to traditional solid PTFE semi-rigid cables.

  • Available with a tin-plated outer conductor

Non-50 Ω Copper With impedances from 5 to 100 Ω and diameters from 0.020 to 0.250”, our semi-rigid cables are the right solution for any impedance-matching requirement.
