Create, optimize and verify 2D or 3D geometry structures that can be used for antenna modelling using this simple and straightforward app

• More general and consistent data-entry when generating nec-2 output. Pre 4.3 version support for raw nec-2 input re-enabled. The new 5.1 4nec2X version also enables real-life structure-geometry and far- or near-field pattern visualization. The use of DirextX based hardware graphics-acceleration delivers you fast rotating, zooming.
• 4nec2 is a completely free Nec2, Nec4 and windows based tool for creating, viewing, optimizing and checking 2D and 3D style antenna geometry structures and generate, display and/or compare near/far-field radiation patterns for both the starting and experienced antenna modeler.

4nec2 is easy to use and comes with a basic 3D editor to help novices create antenna models, compare field patterns, generate SWR charts and learn in the process. However, it also features options.

Especially designed for antenna modelers, 4nec2 is a simple tool for designing, optimizing and verifying 2D or 3D geometry structures.

4nec2 is easy to use and comes with a basic 3D editor to help novices create antenna models, compare field patterns, generate SWR charts and learn in the process. However, it also features options designed to meet the requirements of more advanced users, such as the genetic algorithm based optimizers.

The interface looks rather crowded, but it provides fast access to all the options. It displays detailed information about the antenna parameters, such as the voltage, frequency, wavelength, impedance, the number of series and parallel components, input power, structure and network loss and the calculated efficiency.

The geometry editor provides real-time rendering of the model, displaying a 3D graphical representation of the model and enabling you to rotate it freely, zoom in and out, determine segment lengths or view the wire load.

Auto-segmentation, frequency sweeps. step-radius conversion, adjustable input power, memory usage options, customizable unit types are other features that this application comes with. Additionally, it can calculate area-plot and point plot data and display it on the screen.

The built-in geometry builder enables you to set the configuration parameters (radius, angles, rotation, length etc.) in order to generate patches, boxes, cylinders, parabolas, helices or spheres. The application can evaluate the model and optimize the antenna and other variables, such as the resonance, efficiency, SWR or the F/B and F/R-ratios.

4nec2 is capable of running up to 11000 wires and/or segments and features a powerful real-time 3D geometry and pattern viewer. It is suitable for both experienced and beginner antenna modelers, providing all the necessary tools for designing fully-functional designs.

4nec2 was reviewed by Mihaela TeodoroviciNew in 4nec2 5.7.4:

• Some 300 extra categorized example files added.
• Under certain conditions, in Geometry Edit all wires were saved as single-segment wires. This bug was fixed.
• Bugfix because both Ri and Xi values were extracted from the same Nec Ri data-value when optimizing/sweeping a model containing split voltage/current sources.
• Bugfix when using variable names longer than 8 chars in Genetic Optimizer.
