Review on 🚁 AerialTEK - Copper DJI Signal Booster, Range Extender and Antenna Booster: Parabolic Process for Extended Range for DJI Phantom Standard with WiFi Signal Boosting and Amplification by Nicole Harty

I haven't tried if it extends the range, but my biggest complaint is that it doesn't fit the controller's antenna very snugly. The controller antenna must be in the 90 degree position. to stop it Any small moment on the antenna or controller will cause the range extender to fall. It should have a tighter fit.
