IEC 61196-8-1:2023 Overview
The IEC 61196-8-1:2023 standard defines a blank detail specification template for semi-flexible coaxial communication cables featuring a fluoropolymer dielectric and a tin-soaked copper wire braid outer conductor. It is part of the IEC 61196 series focused on coaxial communication cables used extensively in RF and microwave signal transmission.
This 2023 update presents an important technical revision to align with modern communication needs - particularly for use in mobile communication base station antenna systems, terrestrial microwave communication, radar systems, wireless equipment, and other high-frequency signal transmission devices. The document serves as a foundational guideline enabling manufacturers, users, and national organizations to develop detailed, customized cable specifications consistent with the IEC format and requirements.
