ESP 8266 wifi directional amplifier

Redirecting Wi-Fi signals to a specific direction is now easier than ever. To do this effectively, start by printing out a custom directional antenna. Next, place aluminum tape on the outer surface of the printed design to enhance its effectiveness. Although it may not be as efficient as a parabolic design, this method still works surprisingly well. Once complete, insert the USB power cable into the central hole and carefully place an ESP 8266 module inside.
