This the YO file for the 6 element 10 meter yagis I built. This yagi is on a 24 foot boom. I used tubing I had on hand so the elements are kinda large - the boom is an old Telrex 20M326 so that is why there is about a foot extra sticking out past the reflector. They are based on the NW3Z OWA designs.
