This is a USB-Yagi directional Wi-Fi antenna driven by a power amplifier.

It offers a great range with optimally tuned antenna BALUN impedance.

It can be connected to a Windows 10 or Raspberry Pi computer's USB port and works straight away without CD driver installation.

It could either be powered by an AC/DC adapter or draw the DC current from the another USB port of the computer.

Ideal for drone application, security camera off premises installation, caravan public WiFi access...and for those who are hungry for power and range extension.

Thank you for watching.
