7.5.2. Antenna Cable
Connecting cables between the module and the antenna must have 50 Ω impedance.
If the impedance of the module is mismatched, RF performance is reduced significantly.
If the host device is not designed to use the module’s diversity or GNSS antenna,
terminate the interface with a 50Ω load.
