So I've done the mods on the DJI range extender adding both an 8dBi omni and a 9dBi directional with success. In an area over a lake in a less populated area, I can get FPV out to about 2,000ft / 600m and also start to lose control range with an unmodified remote controler and I'm happy with that. While flying downtown in a major city, likely surrounded by hundreds (thousands?) of 2.4/5.8 GHz WiFi access points in an apt complex, even from my roof, I can only get about 250ft / 75m of FPV (I've never ran out of control range). If I rotate the P2V at just the right angle, I can squeeze out a bit more FPV range, but not much. FPV range was even closer prior to adding the external antennas. So... my question for the WiFi / RF experts, what can I do to increase my limited range specifically in urban environments? Do I need to add an aftermarket range extender? Add a specific antenna and/or booster to the P2V camera? If I could get the 'stock' distances in an urban area (line of sight), I would be thrilled. Is this even possible? Or do I need to switch to different, less utilized frequencies offered by other manufacturers?
