I fly the Phantom 3 pro to do aerial photos. It is very nice to sit in the seat of the car and soak up air conditioning (and be able to see the tablet) while slaving away for the benefit of mankind. Of course I'm having some issues with range because I'm sitting inside a metal can. I found a post that told me I could put a couple of 2.4 ghz magnetic antenna's on the roof of the car and run a set of coax to the controller and end up with extended range to boot. Is there anyone out there that has tried this and that would be willing to coach me? I've read some posts that some extenders will extend the range of the drones control but not necessarily the video range. I'll need both. I'd sure appreciate some advice.
