The program supports about 500 segments out of the box I think, but download the engine files from the same 4nec2 website and you can use up to 11000 segments! Now that would be an antenna! The program has two parts. The 4nec2 base part works fine for 2D, but if you want the 3D modeling, get the 4nec2X download as well. Just install them both.
In 4NEC2, we simulate the monopole along the "Z" axis, perpendicular to the "XY" plane (fig.1). Fig.1. 4NEC2 model of a 1/4 wavelength monopole over perfect ground. In this first analysis we consider a perfect ground and zero radials. The monopole length, as optimized with 4NEC2 to minimize SWR, is 5,16 meters. 1.2. Simulation results.
We will meet once again at Glory Days Grill in PanAm shopping center (near microcenter) at 11:30am for lunch. Our program will be a presentation on NEC (4NEC2) software for antenna modelling. Get all the tips and tricks. Come eat, laugh and learn. See you there.

Sep 11, 2019 · I try to make a 7 el. yagi for 50 MHz. I start with MMANA software achiving a good result. Then I switch to 4NEC2 to confirm result and result are very different. Well now I don't what is true . Before cutting alluminum tube I would like to have a reply. I attach .nec file of 4NEC2 and MMANA result. Thanks Massimo

Dec 28, 2020 · MMANA-GAL is an antenna-analyzing tool based on the moment method, which was introduced in MININEC. Included is a possibility of user's interruption of extensively prolonged processes of calculation, draw plos or optimisation,Improved is a behaviour in crytical situations such as emergency close down, memory shortage or external interruption which can occur during calculations.
That be 4NEC2. Being more powerful, the learning curve is steeper than EZNEC, but is is well worth the effort. I, so to speak, "trained" first on EZNEC and only then dug into 4NEC2.

These files are all in .weq format, and are intended to be utilized in antenna simulation software. They were created and optimized using MultiNEC, v.2.2, a really nifty software package created by Dan Maguire, AC6LA, who has created a truly addictive piece of ham radio software.
Oct 03, 2006 · In order to achieve the largest possible bandwidth with the dipole, it is necessary to match it to a 75 Ohm transmission line. This is because the dipole impedance at resonance is close to 72 Ohms, which is much closer to 75 Ohms, as opposed to 50 Ohms.
EZNEC, Nec2Go, 4NEC2, NEC4WIN, etc. It is well know that the impedance of a resonant antenna only has a resistance component and has no reactance. Since the antenna is resonant, the reactance looking into any other point along the antenna, also has no reactance. The inductive and the capacitive reactance cancel as in a parallel tuned circuit.
I actually like 4NEC2 but haven't used it for this. There are several ways to do the antenna switching, the way I did it or by shunting all but one antenna to ground. The shunt is a biased on diode connected to the antenna a 1/4 wavelength away connected to ground. This needs further investigations as well.

Jan 20, 2016 · The big 3 in ham antenna modelling software are EZNEC, 4nec2 and MMANA-GAL. Apart from these there are YO, AO and also NECWin Plus, NEC2GO. There are other, non nec or mininec kernel based programs. And other EM (electromagnetic modelling) software based on ‘mesh engines’ such as FEKO EM, Ansys HFSS, Sonnet EM which do cost a pretty buck.

In 4NEC2, you can override these frequency settings by choosing the Frequency Sweep option. Once you see the "Press Enter to Continue" line, the NEC input file has been saved in the current folder (where LPCAD is located). I like to place the LPCAD.exe file in the model folder of 4NEC2, so I can easily find the NEC files when I use 4NEC2.
2) 4Nec2 Written by Arie Voors. Has been around a few years and has many nice features. Somewhat trickier to use that EZNEC and you need to watch it carefully. However it is free and has many nice features. 3) SimSmith Written by Ward Harriman AE6TY. New program and still in development but stable enough to use effectively. This

Is there a root available or in the works for the dual-screen NEC Medias W N-05E? The question has been asked (no answer so far) at the end of a thread under the N-05D but that's a quite different model. I'd like to create a separate thread for this model to give it more visibility.
OK, 4NEC2 is driving me nuts. It's giving me results I know are bullcrap. It's giving me negative SWR numbers, reflective coefficients > 0, and negative R impedance values. I understand X impedance can be negative or positive, depending on which way the capacitance and inductance are imbalanced.
