So here it is, the results of my real-world range test having installed on the transmitter and range extender antennas from Horizon FPV and leaving the DJI Phantom 2 Vision completely unmodified.
The Flytrex mission log is here: http://www.flytrex.com/mission/quadcopter-phantom-2-vision-simon-newton-16378/
The antenna kit I used is available here: http://horizonfpvantennas.mybigcommerce.com/phantom-2-vision/
I’m very pleased with the results so far! Although I’m not in the extreme long range game with my quadcopter I’ve managed to double my range in both control and FPV video simply using 50% of the kit, leaving the drone totally stock!
