Stock I was getting around 1200 ft. Yesterday I installed the ARGtek and after a quick test today. I pussed out at 2200. But the live video feed was getting sketchy. And I was getting a weak signal error. Keep in mind this was from my driveway. With some trees between me and my drone. Plus untold interference, being in town. I plan to go try and shoot trains this weekend. My favorite spot, and I have yet to get a drone shot, I only went 1600. I just today realized how to turn off the max distance. However I had warnings of weak signal out there last time I tried. Just the max distance reached. I plan to fly out till I lose signal at that spot, for a proper distance test this time. I'm hoping for a mile, but we'll see.
As for the video cutting out what do I do about that? I was using all 3 flat antennas. I hear of power magic or something that improves video feeds? Not sure the name, or what it even is. An app? I dunno.
