The RP SMA connector can be used to attach a duck antenna directly to the module. IMHO that’s nearly impractical for use on moving platforms as the breakout pins could hardly support the forces caused by the weight and length of an antenna.
With a U.FL connector it’s possible to use WRL-00662 (or an antenna with U.FL pigtail, available from other sources) and mount the antenna to the chassis.
Alternately, a short coax RP SMA male to RP SMA female could be used (well, searching the internet I did not find anything like it).
