Hi guys, having problems getting more than 250metres of range with my pv2, the connection breaks and it RTH, iv never gotten more than 350m away with it. I have updated all the software, controller and phantom, the app on my phone. I have put in new batterys into the controller. Also tried fitting a 2.4Ghz 8dbi tp link antenna Omni directional antenna to the controller and still no improvement. If anyone has any ideas I would appreciate the help. I have also fitted the same antenna to the wifi repeater but have no issues with the picture.
