GraphAO

General Introductory Description

GraphAO is a free utility provided by DX Engineering to allow users of the AO software to graph and compare output files from that program. Graphs can be saved as JPEGs or printed out.

Main Description

Antenna designers familiar with AO know that although it is a very powerful and useful program, the functionality of comparing multiple files or variations of a file really does not exist in the program. GraphAO pulls the data out of AO's output run files and graphs the data. From there you can bring in data from other files to compare changes in a specific design, or the capabilities of one design versus another. View graphs for each type of data stored in the run file, and then save the graphs as image files or print them out to look at later.

While GraphAO is a stand-alone program, it does require AO to be of any use. And as it is really only a simple graphing utility for AO, DX Engineering wants to pass it on to you for free. We want to improve your productivity in electrical antenna design as well as show you the quality and usefulness of our software.

If you are satisfied with this program and are interested in designing your antennas mechanically in addition to the electrical design work you are already doing, we invite you to check out our Yagi Mechanical design software. There is a free trial available, and the full version is only $39.95.

Technical info

GraphAO is a Windows-based application that runs on Java. Check the details below to determine if GraphAO will run on your computer. Any PC meeting the minimum requirements for Java should run GraphAO. DX Engineering's recommended values are what we consider necessary to run GraphAO smoothly, and are the minimum level for which any performance-related problems will be addressed.

System requirements/recommendations:

-166MHz PII class (500MHz PIII class or better recommended)
-32MB RAM (64MB RAM or better recommended)
-50MB HD space (100MB HD space or more recommended)
-Windows 98 or higher, Windows NT 4.0 SP6a or higher, Windows XP, or Windows Server 2003

Applications

GraphAO exists solely as a graphing utility for AO's run files. It makes it easy to see your data visually, as well as compare it directly to other files, and to save the graphs as images or print them out.

It is 100% free, so download it now and try it out.
