Mmana-gal Antenna Files Updated Jun 2026

: General project information, such as "EFHW antenna" or "vertical 20 m".

: Includes the target frequency (e.g., 28.5 MHz), wire material (e.g., copper), and ground setup (e.g., real ground with specific dielectric constants).

: Instead of naming a file yagi.maa , use a descriptive format like 3ele_Yagi_20m_14150MHz_Aluminum.maa .

: Use the built-in Optimizer to let the software automatically adjust wire lengths for the best SWR or Gain. mmana-gal antenna files

The core of the file is the geometry table. Each wire is defined by its start and end points on a 3D Cartesian coordinate system ( ) along with the wire radius.

Lists the coordinates. For example, a simple dipole might have one wire running from (-5, 0, 10) to (5, 0, 10) , representing a 10-meter long wire 10 meters off the ground.

Set your priorities using the slider bars (e.g., prioritize lowest SWR over maximum gain, or vice versa). : General project information, such as "EFHW antenna"

If a wire has too few segments, the simulation will be inaccurate. If it has too many, it will be slow. Use the "Auto-segmentation" feature to stay in the "sweet spot."

To create an antenna file () for MMANA-GAL, you essentially write a plain-text description of the antenna's physical structure and electrical properties. Quick Template: Simple Dipole (.maa)

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? : Use the built-in Optimizer to let the

Modeled with radial systems to check ground efficiency.

If you find an antenna definition online as text, you can often go to Edit > Antenna definition edit in MMANA-GAL and paste the code directly to load the model without needing to download a physical file. Introduction to Antenna Modelling - MMANA-GAL

Go to the menu in MMANA-GAL and select Antenna definition edit .

Specifies how many segments the wire is divided into for the calculation engine. 3. Sources and Loads
