When it comes to the tapering discussion above.  I know how to use it with 4nec2, but I really don't.  The results when it comes to gain and SWR bandwidth will be somewhere in between the two diameters depending on where the current peak happens on said wire.  In most cases the two diameters in question produce results that are very close to each other to begin with.


You can also use tapering to actually vary the length of segments along a wire as well, essentially more segments on one side and less on the other side of a given wire.  While I can see the potential in this, I don't need it as I use enough segments in general to account for this to begin with.  If I had a segment limit I would likely use this feature.
