Mmana-gal | Antenna Files

Specifies the file version and the name or description of the antenna.

: MMANA-GAL can export calculated data in comma-separated values (CSV) format, which can be opened in any spreadsheet software like Microsoft Excel or Google Sheets. These exports can include:

: Defines the feed point(s) of the antenna. A source can be placed at the beginning, end, or center of a specific wire.

The official home for the basic version, which sometimes contains direct examples in their documentation, designed by Alexandre Schewelew.

Open any .maa file in Notepad, and you'll see a few clear sections. Here’s an example of a simple 20m dipole: mmana-gal antenna files

To prepare MMANA-GAL antenna files ( ), you can use the software's built-in tab or manually edit the text-based file in a program like 1. Key Components of an .maa File A standard

: The .mab file is a binary file that stores the results of the last calculation performed on an antenna model. This allows you to quickly revisit and analyze results without re-running the simulation. Unlike the .maa file, the .mab file is not designed for manual editing; it's managed entirely by the software.

Are you aiming to optimize for , widest bandwidth , or lowest SWR ?

If you find a design in .nec format that you want to use in MMANA-GAL, you can use online file converters or use the File > Import option in MMANA-GAL to translate the wire coordinates automatically. Best Practices for Creating Error-Free .maa Files Specifies the file version and the name or

Calculated via fast approximations; excellent for elevated antennas. Highly accurate for wires close to or buried in the ground. Proprietary but human-readable text structure. Standardized NEC card deck format (GW, CM, EX tags). Ease of Editing Very simple geometry tables. Slightly steeper learning curve for raw text editing.

The software primarily interacts with specific text-based and binary formats: (MMANA Antenna) : The native and most common file format. It is an ASCII text file

✅ – Describe the antenna, date, author, and intended band. ✅ Define the frequency explicitly – Always include the frequency (MHz)= line. ✅ Use real-world wire diameters – 1–2 mm for thin wire, 10–20 mm for thick elements. ✅ Set segmentation to -1 – Let MMANA-GAL decide the segmentation for best speed vs. accuracy. ✅ Place the feed point on a wire segment – Not in free space. ✅ Test for convergence – Run the simulation, then double the number of segments. If results change little, your file is stable.

One of the greatest strengths of MMANA-GAL is the active community that shares its antenna designs. Here's where you can find and contribute to this collection: A source can be placed at the beginning,

Always place sources in the center ( c ) or at the exact beginning/end ( b or e ) of a single, well-defined wire. 6. Where to Find Pre-Made MMANA-GAL Files
