N8222WU

To understand the functionality of the N8222WU, one must first understand the basic principles that underpin the antenna. At the core of the antenna is the Yagi-Uda design, which has been in use since the 1940s. In its simplest form, a Yagi-Uda antenna consists of a driven element, a reflector, and one or more directors. The driven element is the antenna element that is connected to the transmitter or receiver and that emits or receives the desired radio signals. The reflector is a device that reflects the radio signals in the opposite direction and the directors are identical antennas that act like lenses and focus the energy that is sent or received in a desired direction.
