By default the Monitor One uses the internal cellular and GNSS antennas, but can be switched to
using the external connectors inside the enclosure.
The cellular (1) and GNSS (4) antennas are not connected internally at the factory. In order to use
the external connectors you must open the case, disconnect the internal antenna, and instead
connect the U.FL connector for the external jack.
The Monitor One is equipped with 2 external-facing SMA bulkhead connectors for both cellular and
GNSS but are disconnected internally. The hardware is ready for use with external antennas giving
the ability to connect a wide variety of application-specific antennas. It is recommended that the
user perform required RF certifications with the selected antenna installed as the Monitor One has
only been certified for use in select regions with the internal antennas.
