– A commercial fork appeared with more features (NEC-4 support, 3D CAD import) but at $149. The free version remained, but development stopped.
: Classic wire antennas for shortwave bands.
When you download and install MMANA-GAL, it comes pre-packaged with hundreds of antenna files. Look inside the ANT folder within your MMANA-GAL installation directory. You will find neatly categorized folders containing files for:
Let’s look at how to build a basic file from scratch within MMANA-GAL, highlighting how the data maps to the file. Step 1: Define the Frequency
Check that wire radius matches your real-world aluminum or copper. Element thickness heavily impacts resonant frequency. Ensure no part of the wire geometry drops below over real ground. Negative height crashes the MININEC processing engine. mmana-gal antenna files
Navigate to the Calculate tab. Here you can set the frequency and click Start to run the simulation.
Switch to the Far Field Plots tab to view the horizontal (azimuth) and vertical (elevation) take-off angles. Modifying and Optimizing Antenna Files
They can be imported into other NEC-based software (like 4nec2) with minimal conversion.
Forgetting to change the default wire radius can vastly alter your tuning results. Copper wire, aluminum tubing, and steel cable behave differently due to velocity factor and surface area. – A commercial fork appeared with more features
This guide explains how to use, create, and find MMANA-GAL antenna files to optimize your antenna designs. 1. What Are MMANA-GAL Antenna Files?
File → Save As → Choose .maa format. Now you have your own custom .
If a downloaded file assumes a element radius of 12mm aluminum tubing, but you only have 10mm copper, you must change the radius in the Geometry spreadsheet. Because element thickness directly affects bandwidth and resonant length, changing this requires a recalculation. Using the Automatic Optimizer
When creating or editing your own antenna files, a few common mistakes can ruin your simulation accuracy: When you download and install MMANA-GAL, it comes
