Make 2 Metee 3 Element Yagi With Gamma Match. Vswr at 1.2 right at 50.275 mhz. Hi there, change the element spacing to 1,2 meters.
Low impedance of a yagi array up to the value of 50 ohms, as required by the most common feedlines used in amateur and other services. Tions are approximately 23/ 16 inches apart. Hi there, change the element spacing to 1,2 meters.
Good Grief, I’d Checked And Double Checked Those Measures.
Build the reflector first, make it 40″ long. You can use your previous feeding methode again. The capacitor of gamma match is about 50pf.
But, The Driven Element Was Off By Almost 1/2″ On One Side.
299,8/f/2*k factor (for 10 meters band using. The three elements were off by about 1/8 inch here and there. The antenna will have a impedance of 28 ohms (j0) the antenna would be about 20.22 ohms now.
Hi There, Change The Element Spacing To 1,2 Meters.

Overall length should be 100 inches. Then slide the gamma tube (capacitor) back and forth within the strap for the lowest swr reading. Use elements with plastic caps on vertical position only.
