1)
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.
5.3.2. Recommended RF Connector for Antenna Installation
If RF connector is used for antenna connection, it is recommended to use U.FL-R-SMT connector
provided by Hirose.
