LPCAD and StressCAD
(9 May 2010)
LPCAD - Log Periodic CAD
Now available for Vista OS!
LPCAD version 3.34 is now available! LPCAD 3.34 should run fine under Windows 2000, XP, and now Vista, however I have been finding a few minor bugs related to the new compiler. Please email me at rgcox2 (at) gmail.com for details.
Download the latest version here.
Here are a couple screen shots from LPCAD 3.31 running in Vista:
I am working on version 3.4 currently. Some of the things that I hope to add are:
1. A 48 x 48 and 32 x 32 pixel Windows icon (in version 3.32)
2. Rounded xyz values and Tau-tapered diameters in SAVE: AO
3. Support for MMANA file format in SAVE:
4. Option to add director element(s) for a Log-Yag design in SAVE:NEC and SAVE:AO
If you have other suggestions, please email me at rgcox2 (at) gmail.com. Thanks!

StressCAD
If you are interested in trying my newest software StressCAD, please download the current zipped file here. StressCAD allows you to analyze the stress of wind on tapered HF Yagi and LPDA elements.
