- Powerful antenna modeling tool using NEC 2 computing engine. Nec2 specifically provide users, either those experienced with the Nec2 processes, or for those who are neophytes but want to model their own antennas.
Nec2Go uses a simplified process for defining the antenna structure and then providing view of the structure, plots (2D and 3D) and other significant data that is pertinent to the design.
This simplified process uses an edit file with equations for all definitions.
