A thought I had and something I just noticed.

I noticed that in my models above the pattern is being shown along the X axis. If I show the pattern along the Y axis for both of them, their is no skewing. This is with both with your model and mine. I could be wrong, but do you know if EZNEC defaults to showing gain along the Y axis? I think 4NEC2 shows the direction with the most gain by default. I do know some models it doesn't default to the X axis...

Something else I noticed between our models. Your trombone section is in line with one set of radials, while mine is not. Looking at pictures of the antennas online, I think the I-10K design is more like your model layout, while the Shockwave appears to be more like mine.

Also, the Shockwave antenna has its radials directly in line with the mast, they are not offset any, again more like my model than yours.

I wonder if these two differences are part of the difference in our models...
