4nec2 Description

  • Graphical 2D and 3D visualization of Far- and Near-field data and Geometry strutures (including circular polarization view).
  • Line-chart visualization for freq-sweep Gain, F/B, F/R, SWR and impedance data.
  • Drag and drop style Geometry Editor to assist the starting antenne modeller.
  • Full Nec2 and Nec4 command support, including GX, GM, GR, GA, GH and surface patches.
  • Capable of running up to 11000 wires and/or segments (limited by the max of 2Gb of windows on-board memory)
  • Support for inclusion of surface-wave component in far-field data.
  • 3D geometry display for surface patches included.
  • Variable substitution included for complete Nec2/4 command set enabling you to model by equation.
  • Sophisticated real-time 3D geometry and pattern viewer showing real wire-radius.
  • AO-style gradient/hill-climbing optimizer included.
  • Genetic Algorithms based optimizer included.
  • Automatic variable sweeper with line-chart output.
  • Automatic convergence tester with line-chart output.
  • Interactive Smith chart visualization for freq-sweeps.
  • Integrated Sommerfeld ground calculations with frequency-sweep.
  • Automatic generation of VOACAP propagation prediction type 13 and –14 antenna files.
  • Automatic coversion of AO (*.ant)and EZnec (*.ez)input files.
  • Insulated-Wire’ and 'LC-trap' loading-types included.
  • Automatic conversion for feet, inch, #awg to meters and elevation/azimuth to phi/theta and reverse.
  • Batch processing for automatic testing, calculation and/or conversion of multiple Nec, AO and/or EZnec input-files.
  • Extensive segment- en geometry validation, such as: Intersecting volumes, Short/thick wires at sharp angle, Unequal segmentation for parallel wires, Too low hight, Large radius or length changes at junctions, etc.
  • Screen grabber for easy cut/paste, print or save parts of the screen, window or form.
  • Geometry builder to create cylindric, patch, plane, box, helix and parabola shaped structures using auto-segmentation and/or equal-area rules.
  • Automatic generation of Stub-, L-, Pi- and Tee-matching-networks (low- and high-pass)
  • Visualization of circular polarization components E(left) and E(right) for far-field.
  • EZnec style MiniNec ground included.
  • Capable of running the default Lawrence Livermore National Laboratories Nec4 engine.
  • Running on all systems from early Windows-95 to latest Windows-Vista
  • More than 450 example files
  • Context sensitive Help-file.
