U.FL to Pinheader Adapter
Select a female/socket (left-hand side connector in the photos) or male/pins (right-hand side) header.
One row of the header is ground pins, therefore only works with boards where every second pin is ground, or otherwise modifications are needed.
The PCB is 16mm x 11mm. High-quality Samtec header.
Below is an example use case where a female adapter is used on DAR 18 PCM input header.
For more information see a post on connecting U.FL and headers.
