Why? To further explore the feasibility of a particular design for HF, exploring the relationship between rotational orientation (aka 'spin') and ground-reflection gains on the bands 20m through 30m. Said prior results may be found here: Iterations on Div; and here Iterations on Tau.
Color Key for Paragraph Text: White (greater contrast) presents information crucial to interpretation. Red presents a delving into various fiddly details about the surounding main text in white. Stuff which I feel some readers may find self-evident, uninteresting, or even beside-the-point. Tidbits I couldn't convince myself to simply delete.
I ran this iteration every 5° of planar rotation. For the most part, 15° would have proven sufficient. Not always, however. So I'm electing to leave all 35 sets of results showing.
It is disappointing to find that performance on 12m nowhere very much improved, except to the detriment of one or both ends of the 10m band. I am motivated to the point of even trading away some gain from 20m if that will help. Also, it would save me no small amount of wire.
And so, that's what I'll try next: Iterations on OD.
