Mmana-gal Antenna — Files
: Always check if the file is in meters or feet before you start calculating your wire lengths. Check the Segmentation
: Stores how wires are divided into smaller pieces for calculation, often in a CSV-style format within the file. 3. File Operations and Management MMANA-GAL basic
When you download and install MMANA-GAL, it comes pre-packaged with hundreds of antenna files. Look inside the ANT folder within your MMANA-GAL installation directory. You will find neatly categorized folders containing files for:
Yagis, log-periodics, and omnidirectional collinears. Beams: Multi-band Yagis and Quad antennas. 2. Online Repositories and Forums

Three factors led to the decline of the centralized MMANA-GAL file ecosystem:
| Section | Description | Example | |---------|-------------|---------| | [COPPER] | Wire conductivity, diameter, color | 0.001, 0.0005 | | [WIRES] | Coordinates (X1,Y1,Z1 to X2,Y2,Z2), radius (mm) | 0,0,0, 5,0,0, 0.001 | | [SOURCE] | Wire#, segment#, type, voltage, R, X | 1,1,0, 1.0, 50.0, 0.0 | | [LOAD] | Wire#, segment#, type, R, L, C | 2,5,1, 100.0, 0.0, 0.0 | | [SPLIT] | Optimization constraints | rarely hand-edited |
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:

MMANA-GAL antenna files are the foundational building blocks of digital antenna experimentation. By mastering how to read, modify, and optimize .maa files, you can simulate endless variations of dipoles, Yagis, and loops long before cutting a single strand of copper wire.
Forums dedicated to long-distance communication often feature threads where builders share .maa files of highly directional Beverage or Quad antennas.
Settings for free space, perfect ground, or real ground (including soil conductivity and dielectric constants). 2. Anatomy of a .maa File
Go to the table at the bottom of the Geometry tab. Type w1c in the "Pulse" column. This tells the software to place the source exactly in the center of Wire 1. Step 4: Calculate and Save File Operations and Management MMANA-GAL basic When you
Store a master copy of your successfully built physical antennas in a cloud-backed folder. If you tune an antenna in the field and adjust your model to match, save it as a "built" version distinct from the "theoretical" version. 5. Troubleshooting Common File Errors
| File Extension | Full Name | Primary Purpose | | :--- | :--- | :--- | | | Antenna Description | The core antenna model containing wires, sources, loads, and all geometric and electrical data. | | .mab | Calculation Results | Stores the results of a calculation run, including impedance, SWR, and other performance data. | | .mao | Optimization File | Stores parameters and goals for the built-in optimizer to automatically refine antenna designs. | | .csv | Comma-Separated Values | Exports data such as current tables, near-field data, or far-field gain patterns for external analysis. |
The first two lines provide the name of the antenna and any user notes (indicated by the * ).
