Mmana-gal Antenna Files [portable] (2026 Edition)

| 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 |

Switch to the Calculate tab. Ensure the frequency matches your target operational frequency.

This line dictates environmental variables. The 0 indicates free space calculation, 10.0 is the height above ground, and 50.0 represents the target system impedance (50 Ohms). 3. How to Create and Edit Antenna Files

MMANA-GAL (short for Method of Moments Antenna Numerical Analysis - GAL) is based on the MININEC engine. It allows users to create a 3D model of an antenna and analyze its impedance, gain, SWR, and radiation patterns. It is widely preferred for: mmana-gal antenna files

This is where the physical structure is defined. You can edit wire coordinates directly here.

A single .maa file stores:

The primary frequency and frequency steps used for calculating SWR and gain. | Problem | Likely Cause | Solution |

: This is the freeware version, available for private, non-commercial use like amateur radio, hobby projects, and education. While free, it's remarkably capable, supporting models with up to 600 wires and 45,000 segments (versions 3.5+). This is generally more than enough for most home-built antennas, including complex Yagi-Uda arrays, dipoles, loops, and verticals. The file is only about 3 MB in size, and after installation, the default language is English, though community-created language packs are available for other languages.

MMANA-GAL antenna files are the essential, portable format for antenna design in the modern amateur radio era. Whether you are using pre-built files from online repositories or designing custom antennas, mastering the use of .maa files in MMANA-GAL will lead to better-performing antennas and a deeper understanding of electromagnetics.

When creating or editing your own antenna files, a few common mistakes can ruin your simulation accuracy:

Placing a source on a segment that does not exist or at a joint where multiple wires intersect can crash the calculation engine.

If your antenna uses traps, coils, resistors, or capacitors (such as a loaded vertical or a terminated T2FD antenna), this block details those lumped components. It specifies their location on the wires and their electrical values ( 5. Ground and Material Settings The final sections define the environmental variables:

| Source | Format | Notes | |--------|--------|-------| | | .maa | Comes with ~30 example antennas (dipole, yagi, quad, etc.) | | Antenna enthusiast sites (e.g., DL6WU, VE3SQB) | .maa or .txt | Rename .txt to .maa if needed | | Ham radio forums (QRZ, eHam, Reddit r/amateurradio) | .maa | Often in zip files | | Your own designs | .maa | File > Save As in MMANA-GAL |
