The number of segments has to do with some experiments I have been running using 4NEC2.  These experiments would take some data from a model, change some aspect of the model, say length, then take more data, then change the model in the same direction the same amount.  I would record the data from all of the models and put it in a spreadsheet to graph out the changes.  For accuracy I need to maintain the segment length to get reliable results, 20 or even 50 segments is just not enough for said data.  Every change in length has to be accompanied by an equivalent number of additional segments.  The changes are so small that starting with the maximum amount of segments some models have, a change might add in one or two more total segments.  I might make such measurements over 1/5 of a wavelength, and potentially in the future even more.  It is long and tedius work, but there is generally a goal, or something to learn.


That being said there are some downsides to all those segments as well, but that is neither here nor there.  That model came from one such experiment.


I can lower the segment count quick and post another file for you, give me a minute.  How about 19 segments?
