  2. Zur leichteren Bedienung hat Arie Voors hierzu eine graphische Oberfläche programmiert mit dem Namen 4NEC2. Dabei wird die Antenne in sehr kurze Stücke = segments zerlegt, auf denen sich der Strom und die Spannung (fast) nur linear ändern kann. Damit lassen sich erstaunlich genaue Simulationen durchführen

  4. Arie Voors, creator of 4NEC2 wrapper 4NEC2 was created by Arie Voors in his long pursuit (early-90's to 2008) to put an extremely powerful wrapper around the public domain NEC2 Fortran code made public by the Lawrence Livermore National Lab in the USA. Mr. Voors donation of his nearly 20 year investment in developing 4NEC2 is one of the great gifts of all time to the Amateur Radio community, and, to the academic RF community
  5. G4CQM's Wave Antennas designs (Homebrew Yagi Projects) represent a quantum leap in Derek's development of the AOWA (Advanced OWA) style yagi beam using a simple Split Dipole as the Driven Element, see Dipoles Explored to expose the myths! There are no bent elements or different diameters to contend with so construction could not be more straightforward..
  6. Gibt es ähnliche Anwendungen, zum Beispiel die ' große 4Nec2 geschrieben von unserem Freund schwedische Arie Voors. Über in 2000 Gemeinsam starten wir um diese Anwendungen zu schreiben und wir tauschten eine Menge code, uns wir ihm beigebracht, 3D zu verwenden und er lehrte uns viele Aspekte von NEC. Dann wir zwei verschiedene Richtungen haben. Ariel schrieb ein sehr komplettes Programm.

Big Thank You to Arie Voors (OCF Simulation) jsanch08. 6. jsanch08. 6. Post Jul 04, 2014 #1 2014-07-04T12:05. The above is a 720p video of the performance of my OCF on 20m band, 2D, 3D and Current Distribution. The simulator that was used to build is Arie Voors 4NEC2. I will send an Inv V 20m benchmark simulation result later. If you do watch the video, it helps to set the resolution to 720p. Deshalb Lob und Dank an den Autor Arie Voors! 2. Richtiger Umgang mit 4NEC2 Es ist wichtig, die Spielregeln für eine erfolgreiche Simulation einzuhalten.

Numerical Electromagnetic Code (NEC) based antenna modeler and optimizer by Arie Voors: 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. Jul 12, 2012 · 4nec2 seems to.

Arie Voors has done a superb job in providing different ways to approach the incremental design process. Any modelling software has some learning curve. By following the instructions and examples provided it took only a few days. My problem was to get a reasonable, low-cost 40-10m attic antenna in a crowded urban setting with metal surfaces everywhere. 4NEC2 enabled me to find the key elements.

Thank you for that, Arie Voors! Nonetheless, as a FLOSS advocate, I am still hoping for Arie to publish the source code. This would safeguard future development should the original developer be no longer around. Even though 4nec2 is coded for MicroSoft Windows™, I.

Having proved the principle I modeled the antenna in the 4NEC2 antenna modeler and optimizer tool written by Arie Voors which can be downloaded here. The antenna pattern wasn't very good so I started to look at other alternatives. I decided on a terminated inverted U fed from one end and terminated at the other. Apart from the size and shape it was similar in principle to a Beverage antenna. packacges, EZNEC developed by Roy Lewellen W7EL and 4Nec2 by Arie Voors with a heavier emphasis on EZNEC. EZNEC is currently version 6 and a demo version can be downloaded from Roy Lewellen's website www.eznec.com . The EZNEC demo is limited to a maximum number of 20 segments. Even with this limitation, it is a great tool to learn to analyze simple antennas such as dipoles, 3 element yagis.

With the view to establish a quick and easy multi-band antenna deployment for portable and camping operations a simple long wire antenna with an earth or earth plus counterpoise arrangement with a 9:1 voltage unun including a tuner or simply with a tuner is one possible solution. With the 9:1 voltage unun and wire lengths suggested in the below tables the antenna should present non extreme. At the August 13th regular meeting, David Sourdis, HK1A, will present an overview of the antenna modelling program 4NEC2 developed by Arie Voors. 4NEC2 can be downloaded from the 4nec2 antenna modeler and optimizer website. If you have a laptop bring it with you to the BARC meeting loaded with 4NEC2. Try it over the next few months before the meeting and have fun with it. A quote from Arie's.

Therefore praise and thanks to the author Arie Voors! 2. Proper use of 4NEC2 It is important to follow the rules of the game for a successful simulation. Namely, NEC works according to the moments method where the antenna structure consists of wires and each wire is subdivided into segments. You must not violate the following rules: The length of each segment must be between 5% and 10% of.

EZNEC is very easy to use and gives great results, especially for simple verticals and dipoles. Arie Voors has done a superb job in providing different ways to approach the incremental design process. EA4FSI-28T1 - Technical Articles. So, 4mec2 you define a LC network in the model, the code will compute loss. If the model has symmetry, as far as possible the axes of the coordinate system will be used as axes of symmetry. Having an optimizer makes it possible to design multiple element. No good for a real contest gun I invested much time in our quad design, using the superb 4NEC2 antenna design program from author Arie Voors (shareware, pse Google this!!!)
