I roughly get 1.5Km range with my Alphas NHA in 2.4Ghz and stock omni antennas.
I’m starting a project in which I need about 6-8 Km range for Video, Telemetry and RC Control using only OpenHD and Pixhawk Cube (Arduplane). Flights will be in the middle of nowhere, so no RF noise of any kind.
I see your long-range flights and I wonder what are the best options:
5.8 vs 2.4?
Antennas in general…
Circular Polarized vs Linear, directional vs omni?
Antenna trackers? Which one?
