Construction of the antenna is quite simple, with a non-conducting boom, and through-the-boom construction. Elements are welding or brazing wire. Impedance matching is fixed in the design through a j-pole driven element. Thu The design of a Yagi (Yagi-Uda) antenna requires proper understanding of how the components are structured and how varying the lengths and position of these components changes the characteristics of the antenna. The components include a driver, reflector(s), and a number of directors. The driver is the single active element which i So the design started with the feed and the elements were built around it. Typically a high gain antenna is designed in the computer, then you try to come up with a driven element matching arrangement for some weird impedance.
