Hi James,

I think you may be out of luck. AFAIK, there isn't a simple conversion since the entire dimensions of the antenna is dependent upon the diameter of the various elements, that is the primary reason people use the modeling software in the first place to find these things out! Changing the diameter of the elements will affect their length as well as the spacing between the elements - there's nothing simple about any of it!!!

Hello All, I am wondering if there is any "simple" conversion factor to use to modify the length of an antenna element from insulated #10 AWG copper wire to anther gage of wire or to aluminum or copper tubing. I don't wish to learn any modeling software at this time I need the information so I can use materials I have on hand to build yagi antennas for 2 meters and 70 centimeters.
