Review on 🔋 Enhance Your XiaoMi FIMI X8 SE Controller Range with Signal Booster Yagi Antenna Extender – Must-Have Accessories by Dan Barrett

Great price. And yes, I have a noticeable signal improvement. Long Version: They appear to be modeled after the Yagi WiFi antennas people use indoors, but miniaturized. What the technical papers indicate is a linear improvement in unidirectional alignment. I have the benefit of testing on a 5.8Ghz analogue RC so not specifically what they are intended for but an observed improvement indicated by less screen impact at distances easily 2-3x longer are. I'm not a radio geek, but I'm very active when I have to, and that suits my inner geek standard. One that goes beyond BS and focuses on the science of the situation. Short version: They work. Grab a set and go for a run.
