3 Installation
3.1 Housing
Mount Atom UAV to a suitable mounting location. The orientation of the device is
discretionary. The housing is not waterproof, and ingress of solid particles and
liquids must be avoided. Should the device get moist, it must be completely dried
prior to further use. If the device becomes wet, it may be permanently damaged
and rendered unusable. Should the device be suddenly cooled, this may result in
the formation of condensation.
3.2 Supplying Power
Atom UAV has two interfaces for power supply:
 USB connector with 5V (DC)
 JST/TFM connector 5-28V (DC)
The chosen cables must be of sufficient diameter to carry the power (1.4 W).
3.3 Antennas
The FLARM system uses a radio communication frequency in the SRD860 band
(≈ 868 MHz) or in an ISM band (≈ 915 MHz) in different parts of the world. Atom
UAV will automatically select the applicable frequency based on the GNSS position.
The following frequencies are used within the specified areas.
Area
Frequency
Europe
868.2
–
868.4 MHz
North America
902.2
–
927.8 MHz
The antennas should be selected for the frequency band applicable in the
geographic area where the aircraft is being operated. Often, such antennas only
cover one band and need to be selected carefully. However, the antennas shipped
with the Atom UAV standalone variant (and listed as suggested accessories in
Section 7) have wide band characteristics and cover the FLARM frequency bands
of all regions, as well as the ADS-B band. Inappropriate antennas, especially
antennas when placed at poor locations, can provide poor system performance.
Note: Atom UAV OEM ships without antennas. The integrator must carefully
select appropriate antennas. Atom UAV will not automatically detect
inappropriate or damaged antennas, including antennas for the wrong
frequency band.
