4.1.1.2  Radio Diversity 
Atom  UAV  supports  radio  diversity  by  using  two  devices  concurrently.  This 
facilitates  achieving  sufficient  radio  coverage  in  larger  airframes  with  RF 
shadowing, e.g., due to large carbon fiber bodies or battery assemblies. In such a 
setup, both devices will emit the same ID (and thus be seen as one aircraft by 
other receivers) while ignoring signals transmitted by each other. 
Diversity can be configured on the web interface under “Configuration”, “FLARM”, 
“Radio Diversity”. It requires defining a primary and a secondary device, where 
the secondary is explicitly linked to the primary through a reference (part of the 
serial number). 
In normal operation, i.e., a device that is not as part of a primary/secondary setup, 
choose the “No diversity” option. This is the default.
