Thus far I have been using only FS models so I can keep a notice on the Average Gain for the model. Helps me tweak without looking a bunch of details and having to try and remember the previous results


I only know how to add a coaxial FL to a Real Earth model using a wire similar to the mast that I set to the diameter of the coax used. Then I use the feed line tool to create the feed line details and connections to the feed point routing it as necessary.


I'll have to think on the idea of turning the antenna up-side-down.


Bob did you look close at the red line current pattern differences in the models I just posted? I didn't say anything, but I found a difference in my model vs. Henry's, and I had the thought that might be what you were hoping to see since I know you are looking at this stuff really close.
