5.3.2. Antenna Requirements
The following table shows the requirements on main antenna and GNSS antenna.
Table 31: Antenna Requirements
Antenna Type
1)
GNSS
LTE
NOTE
1)
It is recommended to use a passive GNSS antenna when LTE B13 is supported, as the use of active
antenna may generate harmonics which will affect the GNSS performance.
