6.5.2. Recommended RF Connector for Antenna Installation

If an RF connector is used for antenna connection, it is recommended to use the U.FL-R-SMT connector
provided by HIROSE.

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.
