It is recommended to use a passive GNSS antenna when LTE B13 or B14 is supported, as the use of
active antenna may generate harmonics which will affect the GNSS performance.
6.5.2. RF Connector Recommendation
If you use an RF connector for antenna connection, it is recommended to use the U.FL-R-SMT
receptacle provided by Hirose.
