So I just installed the kit in the title and I see about 800m range which is absolutely fine. The problem is when I turn around to fly back, I lose signal until I get within ~300m. Best fairly reasonable antenna? Current antenna is mounted so it sticks out the back of the Phantom, so I am not surprised by this. Also, anyone think the height shows WAY to high? When I am level with the gutter on the second floor of my house it shows 15m, should read more like 7m.... I know that its about 20ft high, seems way wrong. Starting point reads about 1m. Anyhow, this has been asked 1000 times, but I found 1000 answers. Real world advice would be good.
