Yagi-Uda antenna

A Yagi-Uda antenna is a type of directional radio antenna designed to focus radio waves in a specific direction. It consists of a main central element called the "driven element" connected to a transmitter or receiver, with several additional rods called "parasite elements" placed parallel to it. These parasitic elements help to amplify signals in a particular direction, increasing range and signal strength while reducing interference from other directions. Commonly used for TV reception and communications, Yagi antennas are valued for their simplicity, efficiency, and ability to direct radio energy precisely where needed.
