Our friend Richard Sisco has put together a video tutorial showing a do-it-yourself antenna modification process for the DJI Phantom 3 Standard drone. He uses 1 APA-M25 and 2 APA-M04 Wi-Fi antennas from Alfa to complete the modification.

See the tutorial video here.

See the range test video here (completed from 14,180 feet).

The first video has a link to the specific Alfa antennas sold by Rokland needed for the modification, as well as other parts you will need.
