This line dictates environmental variables. The 0 indicates free space calculation, 10.0 is the height above ground, and 50.0 represents the target system impedance (50 Ohms). 3. How to Create and Edit Antenna Files Comment: 2m 5-element Yagi | 144
import os for file in os.listdir('.'): if file.endswith('.maa'): with open(file, 'r') as f: data = f.read() data = data.replace('Frequency: 14.150', 'Frequency: 14.250') with open(file, 'w') as f: f.write(data) 10.0 is the height above ground
An .maa file is a plain text file that defines an antenna's physical properties. It generally includes: Introduction to Antenna Modelling - MMANA-GAL
