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.).

To install the antennas:
1. Connect the cellular antenna to the SMA cellular antenna connector.
Mount this antenna so there is at least 20 cm between the antenna and the
user or bystander.
2. 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 90°).
Note: If the antennas are located away from the gateway, 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 gateway over
time.
