Review on 📶 Threeking Foldable Parabolic Signal Booster Range Extender Antenna for DJI Mavic Mini/Mavic Pro/Mavic 2/Spark/Air 1 Remote Controller by Larry Morris

I have a Mavic Mini and before purchasing these signal boosters I did LOTS of range testing in a densely populated area near San Bernardino. My line of sight was always clear and I always flew the same trajectory. My furthest range before buying signal boosters was about 10,000 feet and it wasn't easy because my signal dropped very quickly. But after I attached these signal boosters, I easily reached over 12,000 feet on my first flight and could have gone much further if I had more drone battery. My previous record is over 15,000 feet, which again was limited by the drone's battery life, not the signal. I don't want to risk a low battery crash landing when I get home, so I always try to be safe. The signal at 15,000 feet was pretty solid, 2 or 3 bars. If I had been more adventurous with the battery I probably could have gone much further than 16,000ft. These boosters have worked very well for me and far exceeded my expectations. 5 Stars! Note. Make sure to keep the controller steady and keep it in line of sight from the antennas to the drone, otherwise the signal will drop very easily.
