Discussion Overview

The discussion revolves around the concept of creating a fractional wave tuned antenna or inductor to couple with the Schumann Resonance frequency of approximately 7.8 Hz. Participants explore the feasibility of tuning into this frequency range without the need for large antennas typically required for such low frequencies.

Discussion Character

  • Exploratory
  • Debate/contested
  • Technical explanation

Main Points Raised

  • Jason O expresses interest in tuning a coil to the Schumann Resonance frequency and questions the practicality of using fractional wave antennas to avoid large antenna sizes.
  • One participant questions the nature of the energy Jason O aims to couple with, seeking clarification on its source and form.
  • Another participant shares an anecdote about constructing a coil and claims to have received unusual transmissions, though the relevance to the main topic is unclear.
  • There is a repeated inquiry about the encryption used in the transmissions mentioned, indicating a humorous or skeptical tone regarding the claims made.
  • Jason O reiterates that the signal source is natural and provides a link to a reputable source about Schumann Resonance, emphasizing its legitimacy.
  • A participant acknowledges the source provided by Jason O and suggests considering smaller meter-size antennas as described in the linked article, while also expressing curiosity about other ULF antennas and their construction.
  • There is a side discussion about the "Serial Experiments Lain" reference found in the Wikipedia article on Schumann Resonance, indicating some confusion among participants.

Areas of Agreement / Disagreement

Participants exhibit a mix of curiosity and skepticism regarding the feasibility of tuning into Schumann Resonance. While some engage with the technical aspects, others introduce humorous or tangential remarks, leading to a lack of consensus on the main topic.

Contextual Notes

Some participants express uncertainty about the technical details of constructing antennas for low frequencies, and there are unresolved questions regarding the nature of the energy being coupled.

Who May Find This Useful

This discussion may be of interest to those exploring unconventional antenna designs, the Schumann Resonance phenomenon, or the intersection of physics and speculative technology.

Hello,

I have posted a while ago wondering how to make a coil that was tuned to Earth resonance (~7.8 Hz). I realize that the wavelength at that frequency range is ridiculously low and would require an antenna the size of Texas to couple too normally. But I heard something about fractional wave antennas and was wondering if something like that would work. I basically want to tune into that frequency range to run a small oscillator circuit. But I am wondering if there is anyway to input the signal into the tank circuit without using a huge antenna.

Thanks,
Jason O

What is the energy exactly that you are trying to couple to? I don't mean some pseudo-science energy field. I mean, where is the energy coming from, and what form is it in?
 
This is pretty cool. I ran 500 turns of Cat5 around a 55 gallon drum and started picking up some Martian transmissions. Dang, what is their don de translation...
 
Are they using 32-bit encryption or 64? Anybody know for sure?

No, the signal source I want to tune into is 100% natural, no psudo-science necessary. Here is a link with information about this natural frequency range. It's called the Schumann Resonance.

Hmmm. Looks like a reputable source, and the two-conductor thing sounds reasonable. How about just using the meter-size antennas that the author describes? The article mentions several other ULF antennas -- how big are they, and how are they constructed?

I googled Schumann Resonance and got lots of hits. Kind of interesting. I totally don't get the spoiler warning thing at Wikipedia's page for Schumann Resonance -- what the heck is "Serial Experiments Lain"? I followed the link, but that made even less sense to me :confused:

Looks like a Japnese SciFi cyberpunk cartoon/game.
