7.5.2. Antenna Connector
The LM960 is equipped with a set of 50 Ω RF MHF4 connectors from I-PEX 20449-001.

7.5.3. 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 GNSS antenna, the interface must
be terminated with a 50Ω load.
Minimize Antenna Cable Requirements
Impedance 50 Ohm
Max cable loss Less than 0.5 dB
Avoid coupling with other signals.
7.5.4. Antenna Installation Guidelines
 Install the antenna in a location with access to the network radio signal.
 The antenna must be installed such that it provides a separation distance of at
least 20 cm from all persons and must not be co-located or operating in
conjunction with any other antenna or transmitter.
 The antenna must not be installed inside metal cases.
 The antenna must be installed according to the antenna manufacturer’s
instructions.
Furthermore, if the device is developed for the US and/or Canada market, it must comply
with the FCC and/or IC approval requirements.
