Mmana-gal Antenna: Files

This section defines the simulation settings.

: If a model is giving you "unrealistic" gain, check the segmentation settings. High-accuracy models require finer segments, especially near the feed point. Edit in Notepad : Since they are plain text, you can actually open an mmana-gal antenna files

The file must specify where the transmitter connects. This line includes the wire number and the position along that wire (0 = start, 1 = end). 1 0 1 0 – Means “Wire #1, at 50% of its length (center), 1 Volt, 0 degrees phase.” This section defines the simulation settings

: Defines the feed point(s) of the antenna. A source can be placed at the beginning, end, or center of a specific wire. Edit in Notepad : Since they are plain

MMANA-GAL is a widely used freeware antenna modeling tool. Its native file format (.maa/.maa? or saved project files) and exported formats enable sharing, reuse, and systematic antenna development. This column summarizes what matters when working with MMANA-GAL files, practical workflows, common pitfalls, and quick examples to help hams and RF engineers get reliable results fast.

| Era | Key Event | File Impact | |------|-----------|--------------| | 1998 | MMANA released | .maa format born | | 2002 | MMANA-GAL adds optimization | .gal format with history | | 2005–2015 | Community library explosion | Thousands of free antenna files | | 2015–2020 | Decline (hosting loss, new software) | Files scattered, archived | | 2020–present | Preservation & conversion | .maa as legacy format, still usable |

: Stores data for LCR (Inductor, Capacitor, Resistor) loads or terminations added to the antenna. 2. Standard File Library MMANA-GAL Basic
