7.5.2. Antenna Connector
The LM960 is equipped with a set of 50  RF MHF4 connectors from I-PEX 20449-001.
For more information about mating connectors visit the website https://www.i-pex.com
7.5.3. Antenna Cable
Connecting cables between the module and the antenna must have 50  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, terminate the
interface with a 50 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.
