Additionally, sites like and various DX clubs maintain repositories of proven antenna files that you can download and "virtually" test. Tips for Working with .maa Files
Igor Gontcharenko (one of the developers of MMANA-GAL) maintains an extensive library of innovative HF antenna designs with downloadable files. mmana-gal antenna files
Features robust tools to automatically adjust wire lengths to reach a target resonance. Understanding MMANA-GAL Antenna Files (.maa) Additionally, sites like and various DX clubs maintain
Many videos, such as those detailing EFHW antenna modeling , provide the geometry required to create your own file, such as using 0,0,0 and 17.68,0,10.218 to create a 15m band antenna. 4. Common Types of Antenna Files to Look For When searching for antenna files, you will commonly find: Understanding MMANA-GAL Antenna Files (
Includes ground type (e.g., 2 for Real Ground), height above ground, and the characteristic impedance (usually 50.0 ohms). How to Create Your Own

An inverted-V requires at least two wires meeting at an apex, or one continuous wire split into segments. For simplicity, we will use two wires meeting at a central feed point at 10 meters high ( Radius: 0.8 mm (typical 14 AWG wire) Wire 2 (Right Leg): Radius: 0.8 mm Step 3: Place the Source (Feedpoint)
