I have added 2 x Dlink 9db antennas to the wifi extender to try and get a longer flight with camera view. I live in quite a built up area so I would imagine I get a lot of interference from other WiFi's, is it worth putting an external 9db plus Ariel on the p2v. Would that give me extra flight distance. Also what is the best type of Ariel I use mine with one horizontal and 1 vertical. Are these the best Ariel's to use or are there better ones. I dint want to go miles and miles but at the moment I'm lucky to get 800ft which is disappointing considering I can easily still see it. It would be nice to fly over some woods nearby which are probably about 1100ft away. Any suggestions would be grateful.
