Mmana-gal Antenna Files ⟶ (DIRECT)

Open any .maa file in Notepad. It has five main sections:

| 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 |

Tip: You can edit .maa directly in a text editor to quickly change dimensions, frequencies, or ground type. mmana-gal antenna files

You do not need the MMANA-GAL GUI to modify a file. Any text editor (Notepad++, VS Code, or even plain Notepad) works. However, follow these rules:

Cause: The source is placed at a voltage node. Solution: Move the source to a current maximum (e.g., center of dipole). Open any

An antenna file is just a chunk of metal until you feed it.

MMANA-GAL is a popular freeware tool for designing, simulating, and optimizing wire antennas. Its native file format is .maa (MMANA Antenna). This plain-text file contains all the data needed to reconstruct, simulate, and optimize an antenna model.

A single .maa file stores:

There are three main ways to expand your MMANA-GAL library:
