Review on Foldable Drone Range Extender Signal Booster Antenna - Compatible with DJI Mavic 🔋 Mini, Mavic Pro, Mavic 2 Pro/Zoom, Mavic Air, DJI Spark Remote Controller - 1 Piece by Zane Myers

It's amazing how this small and even cheap part can produce such wonderful results. The photos speak for themselves. Today when I flew the Mavic without the signal extender, I lost the signal at just over 5,000 feet; with the amp connected I hit over 6000 and am still going strong. That's more than 20% more distance. This range extender really works!
