| Error Message | Likely Cause | Solution | | :--- | :--- | :--- | | “Wrong wire data” | A line has 7 numbers instead of 8. | Check for missing radius or segments. | | “Source not found” | The source line references a wire number that doesn’t exist. | Ensure your wire table has that index. | | “Strange SWR” | The segments/wavelength ratio is too low. | Increase segment count on long wires. | | “Optimization fails” | Wire endpoints are not connected. | Run before optimizing. | | “File is empty” | You opened a .maa file saved by a different locale. | Ensure decimal points, not commas (e.g., 2.5 not 2,5 ). |
Antenna designs in this software are saved with the extension. These files contain: Geometry Data : The physical coordinates ( ) of every wire in your antenna. mmana-gal antenna files
You can edit .maa directly in a text editor to quickly change dimensions, frequencies, or ground type. Guide to MMANA-GAL Antenna Files Calculate -> Connect
In this post, we’re diving into what makes MMANA-GAL files so useful, how to find them, and how to use them to perfect your next antenna build. What are .maa Files? At its core, an Cause: You have too many segments for a
Emerging tools like Antenna Magus or CST are powerful, but for 90% of wire antennas and small Yagis, MMANA-GAL antenna files are all you need. They offer the best balance between accuracy and ease of use.
