Straight dipoles. I can't get the Yagi to tune. I have tried the 4:1 Balun method with coax but not able to tune. With the straight unbalanced input to the dipole I get a 1:1 swr on about 129 MHz Suggestions? Shall I shorten the dipole?

    $\begingroup$ Welcome to ham.se! A photo of the antenna in it's testing configuration might be useful here...in my experience Yagi antennas are sensitive to odd* details like proximity to ground and feedpoint terminations, among other things. $\endgroup$
