Antenna Files: Mmana-gal

: Adjust the height or wire length in the software to minimize SWR and maximize gain before you even pick up a soldering iron.

This line defines the simulation environment. It contains six critical numbers: mmana-gal antenna files

The story begins in the late 1990s with a DOS-based program called (Method of Moments Antenna Numerical Analysis), developed by Japanese programmer Makoto Mori (JE3HHT). It was a simplified implementation of the Numerical Electromagnetics Code (NEC-2) engine.
