I was getting a message on the GoAPP that read strong interference , do not fly extended range or something like that , every time I go off the ground , I have Main distribution Power lines & a Cell tower behind my house where I fly & know that probably part of the issue , not to mention I'm in a Sub division & probably a lot of WiFi .
First flight & no message on my phone at all , didn't go very far , because of the wind , but had no issues at all , I didn't install the ARGtec to run distance , I was looking for better reception & got it .
