What It Is

Nec2Go is an NEC2 antenna modeling tool developed by Nova Plus Software. It is positioned for both experienced NEC2 users and beginners who want to build antenna models themselves. It integrates a modified Fortran NEC2 engine into a local desktop application, with editing, viewing, running, plotting, and sweep workflows handled through the main interface.

Core Features and Use Cases

Its key differentiator is “equation-based modeling”: all antenna models are defined through text and algebraic statements. It supports variables, SIN/COS/SQR functions, wire translation and rotation, automatic segmentation, variable sweeps, and the use of variables in wire, source, load, and transmission-line statements. Analysis results can be viewed in the main interface, including run output, SWR, gain, and sweep results, with 2D azimuth/elevation plots and a 3D view available. For transmission lines, it supports coax modeling, loss factors, definitions by physical length or phase length, and user-defined coax entries. Ground models include Free Space, Perfect Ground, Reflection-Coefficient, Sommerfeld-Norton, and Ground Wave.

Ease of Use and Documentation

Compared with traditional workflows that require switching between many NEC2 primitive screens, Nec2Go emphasizes a point-and-click main interface with fewer screens. The source text also mentions mouse-hover tooltips, F1 context help, statement-level editing help, and a Beginners Tutorial, making it relatively friendly to newcomers. However, it depends on the VB6 runtime DLL and is clearly presented as native Windows software, so the underlying technology stack feels dated.

Pricing, Openness, and Ecosystem

The collected information does not disclose pricing, trial availability, licensing, or payment methods, nor does it state whether the software is open source. API/SDK access, third-party integrations, and cloud collaboration features are not mentioned. The known ecosystem mainly consists of the built-in NEC2D engine, Network Designer, Coil Calculator, and coax/ladder-line tools.

Pros, Cons, and Best Fit

Its strengths are strong parametric modeling capabilities, a centralized workflow, complete visualization and sweep features, and context help for NEC2 statements. Its weaknesses are limited information about platform support and modern development workflows, as well as a lack of pricing and licensing transparency. It is best suited for RF engineers, amateur radio enthusiasts, antenna design learners, and users who need local NEC2 modeling.

Access from China

The source text does not specify website access, download availability, or payment conditions in mainland China, so the status is unknown. If access or purchase is restricted, users may consider locally available NEC2 or antenna simulation tools as alternatives, but specific substitutes would need to be verified separately.
