Marconi:
Seems your question “enhances” ?
I quote: Your questions:
YOUR QUESTION:
I can't always be sure, but sometimes I see the model with current phase turned on indicating one thing, and the tabular current log showing another.
(AND
In words, this describes a 5/8 wave model where the Antenna View of the red current indicator with currents turned on, shows a phase change in the radiator just as we would expect. However, when we check the tabular Currents Log in the Currents View...there is no indication of this current shift.
END OF YOUR QUESTIONS
MY answer:
No, the tabular current log is exactly describing what is going on. and is exactly as the red current phase line indiactes.
The second part of your question is also incorrect. It does show...
END OF MY ANSWER.
Your Question:
The point I was trying to make to Shockwave was that Eznec showed the I-10K, 5/8 wave model's tabular data report incorrectly for some reason by indicating there was no cross over noted in the data. However, the Antenna view showed the phase shift correctly for this 5/8 wave model as noted above.
MY ANSWER:
----but there clearly is. The angle goes from rather low angle to 165 degrees at maximum magnitude going futher towards 170 with almost no amplitude.. THERE IS A CROSS OVER POINT !...Its at 90 degrees….however you have to stop thinking that it needs tob e at 0 degrees…its 3D.

Your Question:
My question is why doesn't the tabular currents log below agree and indicate the phase shift correctly in the data for the radiator wire #2. See second image of currents log in the PDF file below where I note: "no phase shift noted"
MY ANSWER:
Well the tabular curent log does agree…you are just interperating the red line wrong.
END OF MY ANSWER.
YOUR QUESTION:
Henry is still thinking my question is about the image, and not about how Eznec indicates the phase and current in the tabular currents log for wire #2, in this case.
MY ANSWER:
Well yes, but dont blame me…I am really trying those two do combine of course.
Stop looking to the side of that red line….look from above and enlarge current.

YOUR QUESTION:
Concerning the spiral model Henry posted earlier. I asked him to explain how that related to Eznec and my question about the tabular currents log not showing a phase shift (reversal or inversion), but he has not answered.
MY ANSWER:
Its important to understand phase and current are different things.
You can have a 180 degrees phase shift. BUT if there is almost no current it is difficult to “spot”. So what i did in the “spiral” thing…was to show you “only” phase…(indeed !)
MY ANSWER:
Your last question is rather easy:
Eznec indiactes the phase and current in the tabular current log with a amplitude and a angle.
And well…i know there are sirio enthousiast...heck im one of them
Good price/quality figure.....
BUt
Regarding sirio …well in the past i have seen some “rigth” advertising but sadly these days
Im afraid I'm not sure if i believe any claims of sirio…
Since they advertise with a 3el having almost 11 dBI and a 4el having over 13 dBI..
Just take a look at the website.
With that said.....i honestly doubt if 2dBD is truthfull.
