Mmana-gal Antenna Files [exclusive]

For amateur radio enthusiasts and antenna designers, MMANA-GAL is more than just software; it is a rite of passage. Originally developed by Makoto Mori (JE3HHT) and later refined by Alex Schewelew (DL2KQ) and Igor Gontcharenko (DL1PBD), this MININEC-based tool has become the gold standard for free antenna modeling.

Summary Checklist

  1. Set Frequency.
  2. Set Units (Meters/Feet).
  3. Draw Wires (XYZ).
  4. Check Connectivity (View Tab).
  5. Add Source (Correct Segment).
  6. Set Ground Type.
  7. Save often.

SWR Plotting: After the initial calculation, use the "Plots" button to see how the SWR behaves across a specific bandwidth. 5. Optimization: Letting the Software Do the Work mmana-gal antenna files

MMANA-GAL antenna files are more than just data; they are a collaborative map of ham radio innovation. Whether you are modeling a "stealth" attic antenna or a massive DX tower, starting with a solid file is the fastest way to ensure your signal gets out. What’s your go-to antenna file?

    Practical Workflow: Creating a File

    Method A: The Built-in Editor

    1. Open MMANA-GAL.
    2. Click the Geometry tab.
    3. Define Variables (Optional but recommended):

      : Before you cut a single inch of expensive copper wire, you can run a simulation of a proven design to see how it performs over your specific ground conditions. Optimization SWR Plotting: After the initial calculation, use the

      Calculate: The engine where you set the frequency, ground type (free space or real ground), and wire material (e.g., copper) to compute SWR and impedance.
