To install the antennas:
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 GPS antenna to the SMA GPS antenna connector.
Mount the GPS antenna where it has a good view of the sky (at least 90º).
Note: ALEOS is configured by default for an active GPS / GNSS antenna. If you are using a
passive antenna, after the router is installed, launch ACEmanager, go to Location > Advanced
and set the GNSS Antenna Bias field to Disable.
4.
For Wi-Fi-capable routers, connect the Wi-Fi antennas to the SMA Wi-Fi connectors.
Note: If any antenna is 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 connector from the router over time.
