Has anyone done or heard of a conversion from the stock Phantom 2 GPS to an external Puck GPS antenna? I fly mostly around cell towers while doing audits, and verifying work. I am having a terrible time with GPS sync around all of the carriers equipment - Verizon, T-Mobile, Sprint, and AT&T. I am seriously considering this conversion, as i have already tried the mod of tin foil, and the wire hide. I would imagine that a puck could be mounted directly on top of the P2 on a stem as there is plenty of room. Thoughts??
