I've read many threads about Mavic Pro2 going three or more miles out without losing reception. I understand that trees and houses between the controller and the drone will shorten the distance so I tried flying at higher altitudes, roughly 250' to 350' but I'm still losing control about 1/2 to 3/4 of a mile away. The drone stops, then begins a RTH. Even though I have the antennas facing straight up in the direction of the craft I get the same results. Most of the time I'm flying from a suburb of Boston where there aren't many tall buildings. Am I doing something wrong? Is there a setting I'm missing? Any help would be greatly appreciated.
