I have the FPVLR long range antenna and am using 2.4 Sunhans boosters on each side (see photo). I have increased performance over stock but nowhere near the signal strength advertised or that I see posted by other pilots. I cannot get beyond about 2000' without signal loss? I had attributed this to my being in an urban area ,Hartford,CT. However, recently I was upstate NY; this area was completely unobstructed and without additional WiFi interference. Even there I lost signal at around 2000'? What I'm looking for really is penetration in congested areas, not to fly 5 miles away. The distance limit is just to demonstrate the difference in performance from other pilots I am experiencing with this equipment. Any advice or suggestions? Thanks in advance for taking the time to help.
