Schumann frequency varies constantly. Time of day? Local Thunderstorm? Sunspot / Flare activity? All cause shifts in the shape / size of the Ionosphere which shifts the frequency.
Nailing it down to a SINGLE frequency would necessarily be some kind of a local average, maybe, but certainly difficult to match even hourly.
Pictured antenna appears to be 28" in diameter. This is about 88" per 'lap'. 10 winds would be about 75 FEET of wire.
Wire pictured appears no heavier than 20 or 22 ga.
Would it help to FLAT wind? bunch up as in the photo?
MAJOR SQUARES = 1" ? If i read that correctly, the antenna pictured is only about 5 1/2" in diameter and makes it MUCH easier to fabricate. The big version I speculated on above, would work hung behind a wall hanging of some sort! But should be up high enough.
Too much is never enough
You've got the right dimensions of the loop I used. It wasn't anything optimum, it was just laying around from a project I did some years ago and looked like it would be good enough for a quick test. The main thing I wanted to convey via the picture is that the current should flow about the perimeter to generate the most far-field for a given diameter.
"Schumann frequency varies constantly. Time of day? Local Thunderstorm? Sunspot / Flare activity? All cause shifts in the shape / size of the Ionosphere which shifts the frequency."
That's my understanding also. I THINK the notion of using a "Schumann generator" is to generate a stronger local field that is not as "contaminated" by various beats from the power grid and such to sooth the listener's furrowed brow. Since it is near-field it shouldn't have to be very strong to prevail.
My sense of it is that most folks dump them in the long haul apparently ultimately deciding that they are not worth the effort. Perhaps a good part of their allure is novelty.

You must either have ESP or be the reincarnation of Carnac the Magnificent. What leads you to that bizarre conclusion? I mean other than being a card carrying tweakaphobe? Lol
"What leads you to that bizarre conclusion? (that folks quit using Schumann generators).
Jess' from reading the threads on AA when it was an active topic. Do you still use one?
