I'm not so sure this antenna is radiating vertically polarized radiation anymore.
In both nec2 and mininec, if I have a straight vertical center fed dipole (or in this case a straight wire on the Z or vertical axis), in free-space, all of its radiation is showing up as vertically polarized, as we would expect.
The thing is, if I take the same wire and put it on either the X or Y axis, both of which are horizontal, again in free space, I am getting just as much vertically polarized radiation as I am horizontally polarized radiation.
Being in free space, the Z axis should act exactly like the X and Y axis, but for some reason, in this case, it isn't. The gain is the same, the total patterns are the same, but the polarizations are coming up different.
When dealing with gain, as the total gain figures are the same in all cases, I see no reason to question those numbers. The only thing I see the need to question is weather the radiation is vertically or horizontally polarized.
This is unexpected, and something that in all of my research on modeling I don't recall ever reading about this variance. This is definitely not something that has been documented anywhere that I am aware of. I have spent way to long trying to make sense of it, and all I can come up with is it is something to do with the limits of the day said programs were developed.
All this being said, with the new evidence in play, I am going to take the side that the super Sinner Antenna is only horizontally polarized, at least until I see evidence that suggests otherwise.
Unfortunately, everything available is based on either Nec2 or Mininec, unless I want to spend quite a bit of money. I suppose I could get Nec4 or Nec5, but there is no guarantee that this has been fixed in said versions of the software...
