Inspired by the antenna booster from leenanj, I created my own one and added a feature that all Mavic users really love: Having it foldable :-)
So I designed the Booster from scratch and ended up in having two parts, that will be screwed together with some M3x25 Hex screws. The screws screw right into the plastic hinge of the left shield. I used an M3 thread cutter to tap the holes.
The reflector was made out of two sheets of 80x57mm aluminium foil. I put transparent self-adhesive foil over it to protect the thin foil. I glued it to the inner side of the reflector shields with doublesided tape.
It folds well together and would make transport more handy.
Since I didn't tried it out yet how big the distance improvement is, please share your experience in the comments.
Love to see your makes!
