I'm looking for some advice on how to troubleshoot a range issue on my inspire 1. I've had it for a week and I'm jealous of the folks posting these flights that are 2K+ because I can't even get half of that with mine. Some background: My primary flight area is a rural farm. I'm piloting from a clear hilltop field out over a 1500 acre tract of corn fields, flying at just under 400ft AGL. While flying, I am facing the aircraft with the remote held up, antennas pointing straight up and parallel to one another, all batteries fully charged. I have an old iPhone 5S with only the DJI app installed, a new iPhone 6, and an android tablet. All three show the same behavior. When I received the inspire, the firmware was outdated. I flew it on that firmware, the latest 1.2, and now 1.3 and all three versions behave the same. Now that all the background is on the table, here's the problem. Even with a clear line of sight to the aircraft and no interference on any channels, 2000-2500 ft is the absolute maximum range before video cuts out. Yep, that's feet, not meters. Even more puzzling is how sharp the dropoff is at the edge of coverage. It goes from full signal to nothing in less than 100ft, losing video but still showing full strength for RC control. I've tried just about everything I can think of and can't come up with anything else to try. I've checked all of the antenna connections on the aircraft, made sure the antenna cables aren't pinched or bent too tightly anywhere. Any thoughts? From what I read in the DJI literature, I was expecting at least 2KM under these conditions and I've seen countless postings of people getting an order of magnitude better range than what I'm seeing.
