Mmana-gal Antenna Files -

You can add extra wires to model pigtails or pigtail counterpoises for EFHWs, setting the length to simulate real coax interaction, such as a 3.8-meter pigtail.

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?

Identifies which wire and which segment receives the RF power.

: A binary version of the antenna data, often found in older or specific project collections. : The primary format for mmana-gal antenna files

If your antenna uses traps, coils, resistors, or capacitors (such as a loaded vertical or a terminated T2FD antenna), this block details those lumped components. It specifies their location on the wires and their electrical values ( 5. Ground and Material Settings The final sections define the environmental variables:

If you download an .maa file designed for 144 MHz and want to use it on 430 MHz, do not just change the frequency number in the file. You must use MMANA-GAL's internal ( Edit > Scale ) so that all physical wire lengths and spacings compress proportionally. Summary Checklist for .maa File Success What to Check Why It Matters File Verification Ensure file ends in .maa , not .txt . Software won't recognize raw text extensions. Source Check

An excellent repository with many antenna examples and user-submitted .maa files, often shared as text files. You can add extra wires to model pigtails

These files allowed hams and engineers to save, share, and tweak antenna models without rewriting NEC cards.

A good file is . Follow these guidelines:

Alternatively, (a stripped-down web version) exists but lacks optimization. What Are MMANA-GAL Antenna Files

Simple 20m Dipole * 14.15 *** Wires *** 1 0.0, -5.15, 10.0, 0.0, 5.15, 10.0, 0.001, -1 *** Source *** 1, 0 w1c *** Ground *** 0 2 Use code with caution. Where to Find Quality .maa Antenna Files

A typical .maa file consists of three main sections:

: Use tools like the Online Polygon Data Generator to create custom .maa data for specific shapes like circles or polygons, which you can then paste into the editor. Sample Structure of a .maa File

💡 If you need complex shapes like circles or arcs, MMANA-GAL only uses straight vectors. Use an Online Polygon Generator to create the many short straight wires needed to "draw" a circle.

This is a comprehensive guide to understanding, creating, editing, and using antenna files in .
