This RP-SMA to U.FL Cable is commonly used to attach WiFi, Bluetooth, or nRFxxx based devices to a 2.4GHz antenna. What makes this unassuming cable special is the slightly longer length of 150mm (compared to 100mm). We found that the extra 50mm makes all the difference when working with an enclosure.
