Before diving into file structures, a quick context: MMANA-GAL is the modern evolution of the classic MININEC antenna simulation code. It uses the Method of Moments (MoM) to calculate current distributions on wire structures. Unlike expensive commercial software (like NEC or CST), MMANA-GAL is freeware, lightweight, and exceptionally fast for wire antennas such as dipoles, Yagis, loops, quads, and verticals.

If you have ever typed “MMANA-GAL antenna files” into a search engine, you are likely looking for pre-built models, struggling with file formats, or trying to understand how to import someone else’s Yagi design. This article is your definitive guide. We will cover what these files are, where to find them, how to edit them, and how to convert raw data into usable simulations.
