The LX60 has two SMA female antenna connectors:
•
Cellular antenna connector: Primary receive and transmit antenna connector
•
Cellular Diversity antenna connector: LTE MIMO and 3G Diversity
The AirLink LX60 with Wi-Fi + GNSS also has:
•
One GNSS antenna connector
•
One reverse polarity SMA male connector for the Wi-Fi antenna.
Sierra Wireless recommends cabling out the antenna.
The LX60 supports 2.4 GHz (2400–2500 MHz) and 5GHz
(4900–5900 MHz) Wi-Fi bands.
For regulatory requirements concerning antennas, see
Note: The antenna should not exceed the maximum gain specified in
on page 57. In
more complex installations (such as those requiring long lengths of cable and/or multiple connec-
tions), you must follow the maximum dBi gain guidelines specified by the radio communications
regulations of the Federal Communications Commission (FCC), Industry Canada, or your country’s
regulatory body.
To install the antennas:
Note: Take extra care when attaching the antennas to the SMA connectors. Finger tight
(approximately 0.6–0.8 Nm 5–7 in-lb.) is sufficient and the max torque should not go beyond
1.1 Nm (10 in-lb.).
1.
Connect the cellular antenna to the SMA cellular antenna connector.
Mount the cellular antenna so there is at least 20 cm between the antenna and the
user or bystander.
2.
Connect a second antenna to the SMA diversity antenna connector.
For 3G networks, the second antenna operates as a diversity antenna, providing a
second receive path.
For 4G networks, the second antenna operates as a MIMO antenna, providing a sec-
ond receive path and a second transmit path.
3.
If used, connect a GNSS antenna to the SMA GNSS antenna connector.
Mount the GNSS antenna where it has a good view of the sky (at least 90º).
4.
For Wi-Fi-capable routers, connect the Wi-Fi antenna to the SMA Wi-Fi connector.
Note: If the antennas are located away from the router, keep the cables as short as possible to
prevent the loss of antenna gain. Route the cables so that they are protected from damage and will
not be snagged or pulled on. There should be no binding or sharp corners in the cable routing.
Excess cabling should be bundled and tied off. Make sure the cables are secured so their weight
will not loosen the connectors from the router over time. In vehicle installations, separate antenna,
data, and power cables from other wiring.
