Here’s a 12 Element UHF Yagi antenna that I designed for my friend, 9w2azv. He’s going to use that antenna for his client, that needs to hit a repeater 10 kilometers away from their location.

Here’s are the measurement for the antenna :

After some tinkering around with GIMP and graphics around the internet, I decided to settle down with this particular design. Hope that it’ll be distributed around the world soonish :
