What is a Yagi Antenna and how is it different from a Panel Antenna?
A Yagi-Uda antenna array, commonly called a Yagi Antenna, is made up of linear wire or rod-type elements, each having a length of approximately 1/2 wavelength. These elements are arranged in a row, with each element parallel to each other. The rear element in this array is called the reflector. The second element is the driven element, which is connected to the transmission line, and all other elements in front of the driven are called directors. The gain of a single Yagi antenna ranges from about 6 to 20 dBi, depending upon the length of the array. Multiple Yagi antennas may be connected together side by side in larger arrays, which may have gains from 10 to 26 dBi or higher. A single Yagi Antenna has a long, narrow profile and UHF Yagi Antennas are usually enclosed in radome tubes to protect them from the environment. Gain, sidelobe and F/B performance of a Yagi Antenna is very similar to a Panel Antenna. The main differences are the appearance and that single Yagi Antennas have appr
