For my own and other members benefits if like to get a conversation going with some clear info about gps and or rc signal concerns Yes j browsed a bit so please don't fire back upset I've tried a lot of websites and searches in here. I'll keep it simple I live In a somewhat congested area where most houses are only 20 ft away but we do have parks for takeoff.. I'm getting a weak rc signal at a significantly lower reach than reported on my phantom 3 p.. I'm not in a city just a regular suburban neighborhood and I'd like to weed out the diy solutions and the commercial solutions that don't actually work... Not looking to go crazy but i think either wifi interference or the congestion of houses may be reducing the ability to reach more than around 800 distance. I just would prefer to go overboard with signal strength for my somewhat basic use to feel more comfortable that i won't lose signal even at low distances but with a reliable product that isn't a custom mod..
