Dude if you are getting that distance with stock controllers, a DBS02 mod from Maxxuav will probably get you in the 15k range a boosted setup will out fly your battery.So I decided to do some testing. I went out to open farmland. See below:
Bone Stock P4 @ 400 feet elevation: 7200ish started to get signal issues. Pushed it to 8473 and it started dropping out pretty bad.
P4 with windsurders @ 400 feet elevation: Same signal issues at 7700. Really started cutting out, going 1/2 or full second without signal. RTH initiated after signal drop at 8594.
So, how peeps are getting 20,000 is beyond me. That is amazing that you do, but not feasible for me.

All depends on interference. I flew 2.5 miles in an open area with the stock controller and no windsurfers. Went to another area and with just some tree interferences was only able to push 7000ft before losing signal and having to throw on windsurfers.
Definitely interested in a boosted setup just to be able to fly farther in the congested areas. Oh and those fancy car antennas!
Great video! I stay on the P4 sideHere is a video I compiled yesterday , both flights were performed on the weekend, we had slight wind gusts but the test went great,
both birds are very impressive, watch the Phantom 4 gaining on P3P quite funny, and of course judge it for yourself,
I flew both birds as far as I could pushing through loss of fpv a few times and eventually completely losing connection to controllers,
they both returned on their own

Could the fact your flying in residential areas, with all those houses and all those 2.4 and 5.8ghz WiFi signals, hotspots and who knows what possibly have something to do with it?I reported range issue in the urban area, RTHed at 475 m distance where my P3P had never had a problem in that area, I fly both in the area as a matter of fact I had never had an RTH on my P3P,
the second flight with my P4 lost signal with the controller and auto returned to home point, this really made me worried as the craft also drifted out of sight before initiating RTH and returning.
I also ran a distance flight with P4 in a rural area and it was incredible making no problem 4.25 km each way and landing with 40% battery life... so there you go, there is definitely something changed in P4 and DJI claims it's all the same, I think they are trying to limit the range within residential area for liability purpose, why I do not know...
Nevertheless the P4 is a fantastic quad-copter if they can make it to match P3P range I would be dancing on a cloud with a case of beer !

I'm seeing the exact thing here. One thing I don't like is I lost or when it goes out, the signal all at once too, but I've seen pics of ppl having 2 or 3 bars which I can't get, my video signal degrades but still showed full signal, until the one time it disconnected. I'd love to see a more realistic approach to these bars graphs, so maybe no matter what, at 900 to 1000 yards it should show 4/5 at least, even mathematically, every 1000 yards to lose one bar would be about right, then by the time your down to one bar, your out 4 kilometers . So one bar should be 1000m as they claim 5 kilometers but I go full to gone in 820m exactly (through trees) I hate that.So I'm starting to notice that I can go a lot farther with completely open line of contact. Once you mix some tree, not even a lot, into the mix, the range decreases 2-3 times.
Are you flying in manual channel mode or automatic. Automatic might do this because it sets higher transfer rate. If you fly manual and set it to 4mbps you should see way better results with not switching channels and changing bandwidthsI'm seeing the exact thing here.
