Antenna Modeling With 4NEC2. Presented to HOTARC. By Craig Weixelbaum. May 22, Basic Modeling Approach using 4Nec2. The goals of this A Beginner’s Tutorial for 4NEC, a NEC2 Distribution. Written and Tested by Scroll down, and find “Latest 4nec2 version ()” under the “Downloads” header. Hello! Does anyone know where I can find some good tutorial/guide to get a basics of how to use 4nec2. I am total beginner. I was able to find.

You can choose which pattern to observe. Equating complex number interms of the other 6. I am pretty familiar with 4NEC2. Thanks ahead of time for your input.

CMOS Technology file 1. In this case when the simulation completes a new window will open that shows the antenna pattern. Synthesized tuning, Part 2: Fill in your details 4nev2 or click an icon to log in: Calculated inductance is If you have a tall tree, there seems to be little reason to spend too much time burying radials in the lawn!


I think that many technically oriented folks can learn to navigate it. If you are beyond this stage and have specific questions about entering antenna simulation input or interpreting results, you can ask them here and someone will likely be able to point you in the right direction.

Look at the antenna text file and see if you understand some of the syntax and meaning of the lines in the file. What is the function of TR1 in this circuit 3.

Try a few more examples and see if you have mastery of this simple analysis. The SWR without additional tuning is around 1. You are commenting using your Facebook account.

This is an 80 meter simple wire antenna. But rather than using another wire, realize that I already have a wire coming back down from the feed point, namely the outside of the co-ax feed itself.

Notify me of new posts via email. Someone may be able to clarify.

What will be the SWR? A command box will open temporarily to show progress of the simulation. How high up should I pull this antenna? The lurker i am. If you have questions, just ask, probably someone knows the answer and would be glad to help. The optimizer or sweeper can be used to change the value of defined variables and generate a collection of output files. It would be good to read how to enter antenna data, but rather than enter a whole antenna file, just modify something you think you understand and see if it does what you think it will.


If I use 75 ohm coax, how long should the transmission line be? In the main window choose Calculate and then NEC output data. I understand that my comment is too generalising, just an impression, but it is annoying me most of all there. How do you get an MCU design to market quickly? My gut feeling is that all this effort is misplaced.

An output file contains the results of a simulation of tutoroal input file. I lose files sometimes in 4nec2, cannot see the logic of that organisation.
