 A Yagi–Uda antenna, or simply Yagi antenna, is a directional antenna consisting of two or more parallel resonant antenna elements in an end-fire array; these elements are most often metal rods (or discs) acting as half-wave dipoles. Yagi–Uda antennas consist of a single driven element connected to a radio transmitter or receiver (or both) through a transmission line, and additional passive radiators with no electrical connection, usually including one so-called reflector and any number of directors. It was invented in 1926 by Shintaro Uda of Tohoku Imperial University, Japan, with a lesser role played by his boss Hidetsugu Yagi.

 Yagi100 Alfa Tango Activator's Photo Gallery {reserved for approved activators} Under Construction {currently contains samples only}

The photo gallery will likely be split into three funny different sections: "Alien" with at least six resonant yagi elements, "Human" with four or five resonant yagi elements and "Little Pistol" with two or three resonant yagi elements!
