Web8 lug 2010 · The driven element of a Yagi is a basic dipole. To construct this you may follow my basic antenna tutorial. Your dipole total height should be: Dipole height in inches = 5616/f in MHZ. Or. Dipole height in centimeters = 14250/f in MHz. Both elements should be equal length with feed points not more than ¼” apart. WebFirst, a caution: since Yagi antenna modelling has developed by text-book use of scientific method – build antenna (hypothesis), measure performance (test), use results to develop equations to fit observations, … WebA Yagi antenna is a directional antenna with at least two elements, usually three, mounted on a boom. The main element is the boom, where everything else is mounted. A Yagi usually includes a driven element, a reflector element, and a director element, all mounted on the same plane.
