With the P2V+ I haven't really ventured outside my 3 acres and 200+ is my maximum horizontal distance. But I have went vertically to 400' a couple times and tonight up to 920 feet. I have lost signal at less than 400' but might have been shadowed by my upper wood deck but not by much. Tonight I was testing and shot up to around 920' standing directly under it and regained it at around 800 and went back up and lost it again and did not get connectivity again until about 500' As I said I was under it directly (within 50') and antenna was horizontal to ground so properly radiating towards the Phantom. Does this seem abnormal? I need to try it elsewhere to make sure I don't have interference but thought I would check with you guys.
