Here is a simplified breakdown of how MMANA-GAL interprets the data:
For ham radio enthusiasts, antenna design is often a mix of black magic and hard science. While many rely on trial and error, the modern amateur has a powerful ally: . This antenna modeling software, based on the MININEC engine, has become a staple in the community. At the heart of its utility are .maa antenna files —the blueprints that allow you to simulate, analyze, and optimize your builds before ever cutting a piece of wire.
If you download a 40-meter dipole file but want to build it for the 15-meter band, you do not need to manually recalculate every wire coordinate. Use the feature. Input the current frequency and your new target frequency. The software will automatically resize all wire lengths and spacings proportionally and update the file. Using the Optimizer
In the source table, define where the power enters. For a center-fed dipole, choose the middle segment of your wire.
: 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:
The title of the antenna and a comment line (indicated by * ). Line 3: The design frequency in megahertz (14.15 MHz).
Many reference files are modeled in "Free Space" to evaluate their pure, unskewed radiation patterns. To see how the antenna will actually perform: Open the .maa file. Go to the tab. Change Ground from Free Space to Real . Input your estimated height above ground.
with open("dipole.maa") as f: for line in f: if line.startswith(('1','2','3')): # Wire definitions # translate to NEC GW card print(f"GW tokens")
Specifies which wire and at what position (e.g., center, start, end) the RF source or inductive/capacitive loads are placed. Where to Find Ready-Made Antenna Files
A user-defined label for the antenna (e.g., 20m Dipole ). Frequency: The target frequency in Megahertz (MHz). 2. Geometry Block (The Wire Table)
This comprehensive guide covers everything you need to know about MMANA-GAL files. From the basic file types and structure to practical usage tips, building a collection, and troubleshooting common issues, this article serves as a complete reference for both beginners and advanced users.
This comprehensive guide covers everything you need to know about finding, creating, editing, and optimizing MMANA-GAL antenna files to perfect your real-world antenna builds. What is an MMANA-GAL Antenna File (.maa)?
