Regarding the FlightAware vs AirNav antenna… I have both. It seems like the AirNav one are getting me more planes. Note: They are still indoor, placed 20 cm apart, and a lot of trees, buildings, etc. are in the way at the moment. The setup is the same for both. Antenna > Uputronics LNA > AirNav green stick > Pi 4B.
The persistence mode was enabled at the same time this morning to see the difference.
AirNav/RadarBox. Max range is ~155 nm
FlightAware. Max range is ~100 nm
