WB6BYU Tape Measure Yagi Dimensions

"I like these dimensions - the yagis have nice, clean patterns. I based them on the W4RNL ten meter yagi designs in his series of articles on three-element yagis. I used the W2PV equations to scale the dimensions to different element diameters. These designs probably aren't totally optimized, but they seem to work well enough for me." - Dale Hunt WB6BYU
