However, the software is only as good as the data you feed it. At the heart of every great simulation is a library of (ending in the .maa extension). Here is a deep dive into what these files are, how to use them, and where to find the best ones.
| Problem | Likely Cause | Solution | |---------|--------------|----------| | | Corrupt or wrong format | Open in text editor; check sections exist | | No radiation pattern | Missing [SOURCE] or ground type "Free space" | Add source; set Ground to "Real" or "Perfect" | | Segmentation error | Too many segments total (>500 default) | Reduce segment count or increase limit in Settings | | Strange gain (0 dBi) | Wires not connected | Check coordinates – ends must touch exactly | | Optimization fails | Impossible goals (e.g., 0.1 m yagi for 80m) | Relax constraints or adjust frequency | mmana-gal antenna files
