An .maa file is a plain-text file that contains all the structural, environmental, and frequency data required by MMANA-GAL to simulate an antenna's performance. Because it is written in plain text, you can open, read, and edit these files using the software itself or any standard text editor like Notepad.
. It is one of the most powerful, free tools for antenna modeling, based on the MININEC engine. But for many, the real "magic" isn't just in the software—it’s in the .maa files that drive it. mmana-gal antenna files
Antenna designs in this software are saved with the extension. These files contain: Geometry Data : The physical coordinates ( ) of every wire in your antenna.
You do not need to design every antenna from scratch. The global amateur radio community has built vast repositories of .maa files that you can download, study, and modify. The Internal MMANA-GAL Library
: Choose copper wire, aluminum tubing, or lossless wire. : Always check if the file is in
MMANA-GAL antenna files are essential for several reasons:
folder within your installation directory. It contains hundreds of models for everything from simple verticals to complex rotating beams.
They can be imported into other NEC-based software (like 4nec2) with minimal conversion. If you share with third parties, their policies apply
If the antenna uses traps, coils, capacitors, or resistors (such as in a loaded dipole, vertical, or T2FD antenna), the properties and locations of these components are stored here. 5. Frequency and Ground Settings
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.
