Phantom 4 Antenna mount

Used Parabola calc. to figure curve. Made a big difference on my drone. Used a quarter of a soda can and just glued it on the back of the mount. Of course you will need to print two. Keep in mind as with most antenna's if you increase gain passively it will be more directional, so keep your antenna's somewhat pointed in the aircraft's direction. I believe this will also work on the phantom 3.
