YAGio - Yagi Design by W8IO


YAGio 1.01 is the most current released version.  YAGio runs under Windows 2000, XP, Vista, Win 7 and likely Win 8.  YAGio is similar to LPCAD, it uses keyboard commands instead of a mouse menu. YAGio allows you to create DL6WU long Yagi antennas on any frequency, typically on VHF and UHF ham frequencies. You specify the frequency, desired gain, type of element to boom mounting, DE diameter and parasitic element diameter, and YAGio does the rest.  You can save these designs in 5 different formats - YIO (used by YAGio), NEC (used by 4NEC2), YAG (YO), MMA (MMANA-GAL)  and YC6 (used by YagiCAD). You can also print the results to your Windows default printer. Please email me at rgcox2 (at) gmail.com if you find bugs or to suggest improvements. YAGio.exe version 1.01 was created on 6-10-2015 at 12:39 pm.  The exe file size is 221K. You may download YAGio101.ZIP here.  

I am currently working on YAGio 1.02.  I will also add file export support for 4 bay NEC models.

I like to use 4NEC2 to evaluate my Yagi models.  It is a very nice, full featured version of NEC2.  You can find the latest version of 4NEC2 here: 
http://www.qsl.net/4nec2

You can also find a faster NEC2 "engine" for 4NEC2. (web site currently unavailable) The NEC2/MP "engine" will speed up computation tremendously in dual and quad core PC's.  A model that took 60 seconds to run in 4NEC2's existing computation engine should complete under 25 seconds using the NEC2/MP engine in a dual core CPU and under 12 seconds in a quad core CPU.

Here are a couple screen shots from YAGio 1.0 running in Win 7:
