AntennaWidth (λ/2): 16' 3-3/8" (4.962m) Feed Point Dimension: 0.12λ. Feed Point Width: 3' 10-7/8" (1.191m) Delta Length: 4' 10-5/8" (1.488m) A Delta Match is intended for matching a driven element to 300-600 Ω balanced feed line. A common dipole, driven from the center and 1/2 λ above ground, will exhibit approximately 72 Ω of impedance ====More information on my website at http://www.fuzzthepiguy.tech=====Here are the measurem Theattached instruction sheet is courtesy of WA5VJB who designed these antennas. It outlines how to build yagis for 144Mhz, 220Mhz, several different 440 band frequencies, 900 Mhz, and 1.2 Ghz. For some of the broader bands (like 2m & 440) you may need to tweak the elemnt lengths slightly, but if you follow the dimensions you'll have very good Herewe take a look at building a short, loaded dipole for 20 Meters, 14 MHz.In fact, this is going to be half of a 2 element yagi for the 20M band.L/C Meter Vay Tiền Nhanh Chỉ Cần Cmnd.
