Hi Tilman

I get over 15km perfect reception using 2.4 GHz XBee and a 14 dBi
linear polarized patch antenna on the ground station and a standard
whip antenna on the aircraft. Do you need any more?

Antenna tracking was no issue for me so far. At long range it is no
problem to manually track the antenna as things go very slowly. At
short range you don't need antenna tracking.


That sounds good enough indeed.

Maintaining line of sight can be tricky of course. But that is a 2.4Ghz problem, no matter what antenna. Where I'm currently flying I can easily get behind dense tree lines and a small hill. :-/
