DB, I asked you earlier what kind of match you got with the model on page 10. I had to change your model to Meters where it belonged. I did that by leaving the data numbers the same and changing the units. Then I think the model presented without errors. I guess you also set the element diameters to .0001 mm in order to help eliminate segment errors, but this is just a guess, because I have no idea what you were thinking or doing.
I have your model in Eznec now, and it looks like what you might have intended at the time. I posted it compared to what I thought you guys were talking about...adding wires. I was wrong again...that is what happens when we try and guess what others mean.
All I recall you posting earlier was some results that showed the model's gain compared to a dipole and the gain (6.00+dbi) was about what Sirio reported for their NV4K. This was the bases of my concession. I still can't be sure I have your model correct as noted on your computer however. Can you show me a model with an antenna view that shows the gain results you described earlier?
I also think that is where I first saw the model had units set to mm's too.
I figured out that your model's units were really set at Meters and not mm's, but I wasn't sure that I didn't use a model of mine to enter in the data by hand...that was already set using mm's, even though I never use mm or Meters as units in my models. I also try and set my antenna in the CB range so maybe some can easily compare any dimensions noted...to what they might already understand like 102"-108" inches as a 1/4 wave length at CB frequencies.
I'm sure you had some idea about the use of adding a feed line and seeing if it too would show CMC's by adding the wire idea from the Eznec Manual that I posted for Bob a while back. I just imagined such an idea as the wires being parasitic and not a physical part of the antenna.
We can see the results in the pattern you got, it does not look right, and your radiator is almost a wavelength long at 9.1 meters...just like Henry noted earlier. But I can wait for you to post the other results that shows us a good match, gain, and angle from your Vector model with wires added that you, Donald, and Bob came up with.
You can't be seriously thinking that Eznec's...add a feed line feature to a model, mucks the model up like we see here...just trying to show currents flowing on the outside of the cone area.
I will now try your other model posted on page 13.
No DB I won't be posting any more of my results, but I do appreciate your work in this discussion. This is your model to prove by showing all of your results that coincide with the comparative results you showed us earlier...with a pattern of a 1/2 wave dipole compared to your Vector model with wires added showing CMC's flowing on the radials.
I've just been trying to guess what you guys were thinking and doing here, like I did earlier, and I don't wish to get caught up trying to guess or change what may be proving 4Nec2 is able to predict how the S4 design works according to your model.
You got upset with me before in a PM I sent you...when I tried to predict what you may be doing wrong, my asking questions, and me making assertions without really knowing. I don't want to get me and you in that position again. I'm trying to be helpful.
