Guys, today there will be a short instruction for quadcopter owners Mi Drone (with a 1080p camera). It's no secret that the reliable reception radius for these 'quads' leaves much to be desired, so I developed antenna amplifiers (reflectors) for the remote control and printed them on a 3D printer. The principle of operation of a parabolic reflector is that point sources of radio waves are reflected from the conductive material of the reflector and converge along the axis of the focus, where the antenna itself is located, thereby amplifying the signal.

Print the amplifiers

You can download the STL model of the amplifiers in the attached file.
After you print the amplifiers, glue a thin sheet of aluminum foil onto them, which can be cut from a Pepsi-Cola can. Use two-component glue Abro Epoxy Steel. The size of the aluminum foil is 94.5mm (height) x 91 mm (width).
Guys, I couldn't accurately measure the oval size of the antennas with a caliper, so the holes for the antennas turned out to be perfect ovals, but in reality the ovals are slightly different, and the antennas themselves will fit very tightly into these holes, so after printing the amplifiers, take a half-round needle file and slightly refine these holes.
After the initial test with these signal amplifiers, I managed to increase the reliable reception radius with a constant video signal to one and a half kilometers.
