The statement is a little bit confusing to diagnose when all the information is not given, and his wording. He said sunhan amps, (plural,) also rf linx. 2 amps on video side? I doubt it, but words mean what they mean which leaves questions.
*Which controller is being used?
Video loss at 2000' on the way back.... Had to restart app to get back.... Sounds like app problem.
*Are you using Go 4? Problems have been reported of go 4 crashing.
* Rf Linx amp, is the amp mounted close to the antenna? If not, that leaves room for extra wifi interference between amp and antenna.
* Rx Gain is maxed. Have you tried it set less than that?
* What location are the sunhans?
* Was the wifi turned off in the house? Also other devices? Phones, tablets, laptops...
* Is video feed quality turn down in the app, or is it max? Down = less processing needed = more range. (From what info I've gathered in this thread)
* How congested is the area with interference.. power lines, other wifi..etc.?
* How far apart are the antennas mounted? Have you tried a different spread?
* Are the cables aftermarket?
* Connections tight?
* Clean install connections tight?
List goes on. A lot can be done to improve his, or anyone else's situation.
May not expect the same results with different components too. Jeremiah has gotten 20,000+ with L-coms, old black sunhan on video side only, and an old P3 remote. Hes also using an inspire 1 remote in the house. Different components, different area is going to have different results. BUT, I'm certain that what Bear has to work with can be fine tuned to get the most out of it and the more experienced could help if he would give more detail.
A lot to check and consider before it could be ruled as bad luck.
