Hi to all. I have anout 15 hours of DJI Phantom 4. Today i try to get a bigger distance from my P4 So i go up to 100m - 140m High and when i start to take distance after the 1500m i start to have all the time the "Transmitter Signal low" until the signal was tottaly lost and the P4 return to home as i have in my menu.. I have the latest firmware and this is the first time i try to go f=urther thatn 500m that i usually fly.. I was in a high place so all the time the antennas was looking at the P4.. Any ideas? I read afor about 3-4000m distance...and i think that i have a problem? The maximum i get is 2000m today and auto RTH. Regards!
