Yagi Antennas ExplainedA practical guide to beam arrays from 20m to 70cm \n\nBy Mike Parkin, G0JMI\n\nYagi Antennas have become commonplace in amateur radio since \ntheir invention in the 1920s by Shintaro Uda and Hidetsugu Yagi. These \ndirectional antennas, consisting of two or more parallel resonant \nantenna elements, provide, as Radio Amateurs know, great performance \nacross a variety of bands. If you have ever wanted to build and \nexperiment with Yagi beam arrays then Yagi Antennas Explained is for \nyou. \n\nYagi Antennas Explained is a practical guide to the design,\n operation and construction of Yagi beam arrays for the amateur bands \nfrom 20m to 70cm. Rather than using mathematics, where possible, \nexplanations have been used to describe the operational aspects of beam \narrays. So, you will find explanation of gain, front to back ratio, feed\n point impedance, polarisation, radiation pattern and bandwidth. \nAntennas need to be connected to the radio equipment using fs
