You`ll get the same high gain and nearly equal front-to-back ratio at far, far less than half the price. Efficiency of close to 100% on 20M and 40M bands have been achieved. The radiation patterns are broad and clean at low elevation angles which result in excellent azimuth view in excess of +/-45 degrees. 4m for boom size, what is the range one could expect, in the differences between front-to-back, and gain, when adjusting elements? Is it going to be about 1db gain, up or down, vs something like 20db to 25db front-to-back? Just throwing out some figures, for examples. Heavy duty. 3el 20m yagi
