Mmana-gal Antenna Files [new]
If two wires are meant to touch (like the radial of a vertical antenna connecting to the main radiator) but their coordinates are off by even a millimeter, MMANA-GAL will treat them as open circuits.
In the world of amateur radio and antenna engineering, the ability to simulate a design before cutting a single piece of wire is invaluable. For decades, the industry-standard method for antenna simulation was the Moment Method, a complex mathematical approach for solving electromagnetic field problems. Among the many software tools available, few have achieved the accessibility, power, and community support of .
Specifies which wire and segment holds the feed point. w1c means "Wire 1, Center."
Select your targets (e.g., minimize SWR, maximize Gain, or maximize Front-to-Back ratio). Choose the elements/wires you want the software to change. mmana-gal antenna files
Choose which elements or coordinates the software is allowed to change (e.g., element lengths or spacing).
If you are looking to dive deeper into custom modeling, I can help you format your physical dimensions into a structure that MMANA-GAL understands. To help me tailor the next step, tell me: What are you currently trying to model? What is your target operating frequency or band?
If you are building a library, look for these specific high-performance files: If two wires are meant to touch (like
Because MMANA-GAL is so popular, many tools can convert standard .uon , .nec , or .ez (EZNEC) files directly into .maa format, giving you access to decades of legacy antenna designs. Best Practices for Managing and Using Antenna Files
The third line ( 14.15 ) dictates the design frequency in MHz.
However, the software is only as good as the data you feed it. At the heart of every great simulation is a library of (ending in the .maa extension). Here is a deep dive into what these files are, how to use them, and where to find the best ones. Among the many software tools available, few have
If your imported file resonates at 14.100 MHz but you want to use it exclusively for CW at 14.025 MHz, you do not have to guess the new lengths manually. Click the button.
The primary file types you'll encounter with MMANA-GAL include:
Click to choose which variables the software can change (e.g., wire length, spacing, or height).
MMANA-GAL is an antenna-analyzing tool based on the moment method, first introduced in the MININEC (Mini Numerical Electromagnetics Code) program. It began as a Japanese-language program called MMANA (Macoto Mori ANtenna Analyzer) and was later enhanced and translated by a team of developers, including Alexander Schewelew (DL1PBD) and Igor Gontcharenko (DL2KQ). The software's modularity and ability to be extended by its user community have made it a mainstay of both hobbyist and professional antenna design.
