... What design plans would you use? Thanks joe Are you an Internet only type of person? The original design was perfected by Steve Powlishen, K1FO, who spent hundreds of hours optimizing yagi designs on a high powered Hewlett Packard computer. He started with some computer optimized designs of Tom Kirby, W1EJ, (SK) who was using computer software developed at Ohio State University. W1EJ had came up with many excellent VHF long yagi designs. The finished K1FO designs were carefully checked out in the real world by K1FO to ensure accuracy of the design effort. His efforts have produced an exceptional design with maximum gain very close to the maximum amount possible, while keeping side lobes, (particularly those of the H-plane) at a very low level. The net result is broad bandwidth, wide beamwidth, and clean lobe structure. Clean H-plane patterns translate to efficient stacking with maximum possible gain and manageable array side lobes. The design has been published in MANY printings of the ARRL Handbook. gb |
