6.4. Antenna Installation
6.4.1. Antenna Requirements
The following table shows the requirements on main antenna, Rx-diversity, Wi-Fi/BT antenna and GNSS
antenna.
Table 45: Antenna Requirements
Antenna Type

1)
GNSS
NOTE
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.
