Open any .maa file in Notepad, and you'll see a few clear sections. Here’s an example of a simple 20m dipole:
When you open an example antenna file from the library, it's important to note that these files are typically read-only in their original location. To edit and save changes, you should use File > Save As to create a new copy in a separate directory.
If you are using aluminum tubing of different diameters (common in Yagis), you can define a "taper" to accurately reflect how the element’s diameter changes from center to tip. 4. Running the Simulation (The Calculate Tab) mmana-gal antenna files
There are three main ways to expand your MMANA-GAL library:
Always set the ground to "Real" for antennas lower than Open any
Despite its professional capabilities, the is a fully functional antenna laboratory for most radio amateurs. It includes:
Understanding this anatomy allows you to troubleshoot models or make quick manual adjustments. 1. The Header and Description If you are using aluminum tubing of different
Any coils, capacitors, or traps used to tune the antenna. Frequency: The design frequency for the calculations. 2. Finding and Importing Files
If you find a .maa or .gal file today — treasure it. It represents a simpler, more open era of antenna design.
