Hi, I often do long distance runs where I push the limit. One thing I've noticed on these flights is that I can have full signal at 2 miles out and then as soon as I turn the aircraft around, to head home, I lose the videosignal. Sometimes I even lose the connection to the aircraft it self, engaging the RTH function. And sometimes I won't regain the signal before I'm half way home? Why is this happening? Why is it so sensitive to turning?
