Connection for very thin wires
1.32mm is a common RF Cable size 50 Ohm up to 6Ghz used inside wifi devices. It commonly connects to PCB mount U-FL connector, also supports MMCX connectors and SMA. We're using this cable to connect MMCX connector on a wiFi card inside our wifi router to the SMA antenna connector on the outside, and to do the same thing from U-FL connector on another WiFi card.
