Download MMANA-GAL for free, browse the example files, and open one in Notepad. Modify a coordinate, save it, and run the simulation. You will quickly see why this file format has endured for decades. mmana-gal antenna files
. The software typically includes a library of standard designs located in the MMANA-GAL\ANT\ directory. : Contains basic dipoles (e.g., for 20m) and verticals. VHF simple : Contains 2m and 70cm models. Beams/Yagi : Includes multi-element directional antennas. 2. File Architecture (Geometry Tab) The core of an file is the table, which functions like a spreadsheet. : Defined by start points ( ) and end points ( ) in meters. Radius (R) : The thickness of the wire in millimeters. : Specifies the feed point (e.g., "w1c" for wire 1 center). : Defines LC traps or resistive loads. 3. Basic Workflow for .maa Files Select Frequency tab, set your target frequency (e.g., 14.15 MHz). Ground Setup : Choose between Free Space (no ground), (ideal conductor), or (standard earth). Run Calculation to generate numerical data, including , impedance ( ), and gain. Far Field Plots ; 1/4 wave vertical over perfect ground 14
