Connecting the antenna and the copter in mission planner 1.3.75

Hello all,

Our group build an antenna tracker and follow all the setup in the documentation.
In the mission planner (version 1.3.75 ), we can see the antenna and the copter separately but if we trying to connect them both we can not success to track after the copter.
What is the missing step or what is the right way to connect both and tracking after the vehicle.

Thanks for all,
Reali Drone program.

Have you tried to update the mission planner to the latest beta release?
