So I recently installed the ARGtec antennas on my phantom. I have the directional antennas for the video and the omnidirectional for the ac. On good days I have a hard time reaching past 4000 feet. I know that is good range but I was hoping for more and that's losing video around the same time as control. I seen videos of the same drone going much further and I have read of people getting miles out of them. I also have had twice where i was flying well within range and would suddenly get a disconnected message on the app and loss of video but the drone was still flying fine.
