Antenna Modeling Software. EZNEC Pro/2 NEC-2 Based Analysis Program and EZNEC Pro/4 NEC-4 Based Analysis Program. EZNEC Pro/2 is a complete, easy-to-use analysis program which uses an integrated version of NEC-2 for calculations. Several of its many features are shown below. Here is a list of best free antenna design software for Windows. Through these software, you can design various types of antennas like Yagi, J-Pole, Parabolic, Quagi, Super Scanner, etc. Each antenna design software is slightly different from each other as each software design some specific types of antenna. Antenna Modeling Files To be used with either NEC-4 or Yagi Optimizer modeling programs. While YO is no longer available,.YAG files can be converted using the MS-DOS based SCALE.exe program that appears in the YAGIS subdirectory when YW is installed. YW comes with the ARRL Antenna Book. G4FGQ's Software. The only difference between the demo and standard programs is that the demo program allows only 20 segments, which limits the complexity of antenna you can analyze. 6.0 allows 500 segments, and EZNEC+, 2000.). NEC-BSC Basic Scattering Code, V4.2; NEC-BSC Workbench; OSU Reflector Antenna Code Version 3.5; NEWAIR Aircraft Code, Version 3.1; Current Price List. Below is a price list for available computer codes. Some of the codes may have restricted distribution - see the ordering instructions for additional information.
Nec 4.2 Antenna Software
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.
When running frequency sweeps, linear or logarithmic style SWR, Gain, F/B-ratio and impedance line-charts are produced. With the
included Optimizer and Sweeper one is able to optimize antenna- and/or other environment-variables for Gain, resonance, SWR,
efficiency and/or F/B, F/R-ratio. With the sweeper one is able to graphically display the effect of changing one or more of these variables
for a specified range of values/frequencies.
For the starting modeler agraphically based 3D geometry-editor is included which requires no additional NEC knowledge while still
enabling you to create and visualize and compare current-distribution, far/near-field patterns and Gain/SWR charts. More experienced
modelers can use the gradient style and/or the genetic algorithm based optimizers to improve their designs.
