The following are construction details of a 5 element 20 meter monobander antenna originally published by VE3GK.
However, this particular yagi was run through a computer program and performed very well. It was also scaled to 70 cm on a test range by the late VE3UD, Bud Punchard and the results compared with the computer and more importantly with my actual tests on the air where the real testing is done.
Is boom isolated from the elements or not?
I am on the search for a 5 or 7 element 20 meter full size yagi used.
