You can further read the _GetStarted.txt text-file included in the 4nec2 package. Cebik (W4RNL), both available on the internet. \4nec2\exe folder, in your Word or Wordpad text editor.Other recommended sources for NEC related informations are the Nec-2 and Nec-4 user-manuals and the excellent collection of antenna-modeling articles by L.B. To print this file, open and print the file 4nec2.rtf, located in the. For easy reading the content of the 4nec2 help-file is also available as a (rich)text file.

In all the forms you can process the general buttons F1 to F12, Ctrl+O and Ctrl+Z / Esc. However this version requires a more modern computer-system and graphics-card. To get specific (context sensitive) help for a certain window/form just push the F1 when the form/window is on-top.When the 4nec2X eXtended version is installed the real-time 3D-viewer is also available for use. These options are discussed in more detail further on in this help file. However there are some options who are more difficult to understand. Try out each of these menu-options and see what the results are. Most of these menu-options speak for themselves. Each form contains a menu bar with menu-options.
#4nec2 optimizer plus#
Considerable effort was taken to get used to 4nec2 without the need to first read the complete help-file.The 4nec2 tool consists of four general forms/windows: Main, Geometry, Pattern, Line-chart plus an Edit-, Matching-, Smith-chart and an Optimizer/Sweeper form. So one is able to (textually) create NEC based geometry structures and know something about the results when using GN, EX, LD, and FR cards.Although this help-file might look comprehensive, this is not directly related to the complexity of the 4nec2 package but much more to the large amount of features available.
To be able to use one of both optimizers or the sweeper, some basic knowledge about the NEC syntax is required.
With the sweeper you are able to graphically display the effect of changing one or more antenna- and/or environment-variables for a specified range of values/frequencies.For the starting antenna-modeler a graphically based 3D geometry-editor is included which required no additional NEC knowledge while still enabling you to create and visualize current-distribution, far/near-field patterns and Gain/SWR charts. With this optimizer you are able to optimize antenna- and/or other environment-variables for Gain, resonance, SWR, efficiency and/or Front to Back ratio. Also SWR, input impedance, F/B- and/or F/R-ratio for a range of frequency's on a linear or logarithmic graph (or Smith-Chart) can be displayed.Furthermore an optimizer and sweeper is included. #$KNEC visualization, optimization and sweeping toolThe 4nec2 tool is a windows- and Nec-2 or Nec-4 based tool for both the starting and experienced antenna modeler that can be used to create, view and check your antenna geometry structure and generate, display and compare near- and far-field radiation patterns.
