YAGio - Yagi Design by W8IO

YAGio 1.01 is themost current released version. YAGio runs underWindows 2000, XP, Vista, Win 7 and likely Win 8. YAGio is similar to LPCAD, it uses keyboard commands insteadof amouse menu. YAGio allows you to create DL6WU long Yagi antennas on anyfrequency, typically on VHF and UHF ham frequencies. You specify thefrequency, desired gain, type of element to boom mounting, DE diameterand parasitic element diameter, and YAGio does the rest. Youcan save these designs in 5 different formats - YIO (used by YAGio),NEC (used by 4NEC2), YAG (YO), MMA (MMANA-GAL) and YC6 (usedby YagiCAD). You can alsoprint the results to your Windows default printer. Please emailme at rgcox2 (at) gmail.com if you find bugs or to suggestimprovements. YAGio.exe version 1.01 was created on 6-10-2015 at 12:39pm. The exe file size is 221K. You may downloadYAGio101.ZIP here.

I am currently working on YAGio 1.02. I will also add file export support for4 bay NEC models.

Ilike to use 4NEC2

Online Yagi Antenna Design Program

to evaluate my Yagi models. It is a very nice,full featured version of NEC2. You can find the latestversion of4NEC2 here:

Yagi Antenna Design

You can also find a fasterNEC2 'engine' for 4NEC2. (web site currently unavailable) TheNEC2/MP'engine' will speed up computation tremendously in dual and quad corePC's. A modelthat took 60 seconds to run in 4NEC2's existing computation engineshould complete under 25 seconds using the NEC2/MP engine in a dualcore CPU and under 12 seconds in a quad core CPU.

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