As a result of the first part of my series in QST on Modeling with NEC, I have received a number of inquiries about the NEC4WIN (Lrion/Boukri) web site. Between the time I wrote and the time Part 1 a
Thanks to several folks for supplying me with the correct URL for NEC4WIN Windows MININEC software: http://www.orionmicro.com All links to NEC4WIN/Orion have been changed at my site and QST has been
The last of the log-cell Yagi series in NCJ has now appeared and has been placed at my site, along with the usual monthly new items. However, a study of long-boom potentials for the log-cell Yagi, wh
To the quad model collection of notes, I have added a new item on alternative common feed systems for multi-band 2-element quads. Hope it (item 4a on the sub-index) is useful to those interested in t
My receipt, which goes back to January, 1997, lists the following address: Lawrence Livermore National Laboratory Attn: Gerald J. Burke, L-156 P.O. Box 5504 Livermore, CA 94550 an old e-mail address
For those interested in such designs, I have placed Part 3 of the Log-Cell Yagi study at the site, since it has now appeared in NCJ. Because ARRL owns the copyright for the 2-part series on 3-octave
As a study item, I have added to the "modeling" section of the web site some notes on a 3-30 MHz LPDA with high Tau and Sigma values--a. for the fun of it, and b. as a reference or baseline for the 2
Because the item has now appeard in the Top Band Anthology, Vol. 2, I have posted something smaller than a 1250' LPDA--this time an "ideal" back-up antenna for 80-20 meters--just an 88' hunk of wire
I just put a very brief note at the site with a quotation from "The Old Man" from Feb, 1932, QST. There he mentions the Wouff-Hong (which I have seen), the Rettysnitch (which I have seen) and the Ugg
I have received from ARRL HQ photos of the Uggerumph and further accounts of its origins. I have added some speculative history on how the instrument came to be viewed as animate and self-propelling
Pete, Although there might be a number of reasons for the lack of convergence, let me suggest a few checks. 1. When using the tapered-diameter schedule for the elements, only the elements within 15%
There is a way for modeling systems having an equation-based input system. Tight now, I think that is restricted to AO and NEC-Win Plus among the common programs, although interfaces developed by ind
I have placed part 2 of the log-cell Yagi series at the site, since it has now appeared in NCJ. Hope it is some use to someone. -73- LB, W4RNL L. B. Cebik, W4RNL /\ /\ * / / / Tel: (865) 938-6335 143
In a note to one of these lists--in answer to an inquiry about rotating a beam over a fixed beam--I outlined all too briefly a technique for rotating a beam model. I have since put the note into a be
I recently added 2 items to the "lower HF" collection at the web site (URL below), one on using multi-wire elements as substututes for large tubular elements, and the other on some modeling I have do
In the last couple of days I have added some new notes to the site--one on Moxon rectangle patterns at low mounting heights, the other on an improved 3-element quad design. THere have been some other
There has been a need for exemplary models for both newer and experienced antenna modelers. I have gleaned from my accumulation sets of models that may serve as a foundation for modelers to build upo
I have had some questions about the collections of .EZ and .NEC files that may be more general in interest. 1. The files are for NEC-2 and other advanced NEC cores. THey are not designed for MININEC
