I have done the aluminum foil mod, and now I'm getting more satellites than ever before. I have boosted the FPV signal with V+ Booster, and I am getting a strong, consistent FPV signal at greater distances than before. My problem seems to be a weakness in the basic control signal. Twice in the last week, I have been forced to RTH after a "control signal lost" warning. In both cases, my bird was less than 300 meters from home point. Admittedly, I was operating in residential neighborhoods with numerous Wi-Fi signals and deciduous trees in full foliage, but 300 meters seems like an awfully short distance for losing control signal. Should I consider a high-gain antenna mod?
