DJI Mavic Mini / Pro / Air / Spark Range Booster

thingiverse

Range extender for DJI Mavic drones. Designed for the Mavic Mini controller but I believe most DJI drones have the same antenna design so it should work on most. I used reflective foil tape as a backing. The antenna grip must be printed using flexible filament / TPU. It should fit snuggly into the hole on the extender as shown in the picture. Let me know the results if you try this out! I did two different test flights with them. On one I was able to get 1,000ft farther than without the boosters and on the other I got 400ft farther. Results will definitely vary depending on conditions but they do seem to work. Update 3/25/2020 - Increased the size of the opening on the antenna grip by 0.5mm. This makes it much easier to slide onto the antenna but still grips it well.
