Using the 4nec2 software I was able to find lowest swr for all the foundation bands. Most bands are still above 1:2 though. My measurements show to put the feed point at 28.5% instead of the 30%. Hopefully get it up soon. 73 cheers 4nec2 full is a Shareware software in the category Miscellaneous developed by [email protected] (Use "4nec2 modeller" as the subject). The latest version of 4nec2 full is currently unknown. It was initially added to our database on 03/13/2011. 4nec2 full runs on the following operating systems: Windows. It has a range of 6-32pF. Since the two sections are put in series, the range is actually 3-16pF. This gives the loop a tuning range from 15 through 10 meters. To use the loop also on 17 and 20 meters I made two fixed capacitors from RG58 cable. Software > . 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. The method I am going to use is a Antenna modeling (software) program called 4NEC2. This program is based off the Numerical Electromagnetics Code for modeling antennas. The great thing about 4NEC2 is that you can model almost any antenna and the best part is that its FREE!

We’re just editting together a new set of lessons as well – they will be online in a couple of weeks. Unlike other software platforms that force you to get a new license for every user, Asta allows you to limit your licenses to the number of people using the software at the same time. Yep. 4NEC2 will open .EZ files from EZNEC directly. I'm not very familiar with MMANA-GAL but it appears that Ari's utility will both import and export .NEC files. Any tutorial from any vendor is useful. There's no reason to just use one modeling program. If you had a workshop, would you use one tool for every job? Probably not. using a single antenna. More than that, the better your antenna is, it will have a better selectivity, thus receiving a single frequency. The Gray-Hoverman antenna has been designed by Doyt R. Hoverman and it was patented in the sixties. His design only covered a part of UHF band. However, with Without some good test equipment all the modelling software in the world is useless if you can't prove your designs.
