Lords of the Ring

hello all

i think i finaly got a much better handle on it and it is not at all my ring i put it aside now time for a new 1 this time the right 1 i hope!! but learning is what is all about!!

well yes, i was aware of the paragraph .. but not him saying Dia/Circum.=ideal Freq. .. I merely read the parts in italics .. the bold seems like "guessing" or summarizing.

The important difference here is that in the case of the radio, you tune into the frequency and amplify it for use. In the case of my power unit, you create several frequencies within a space of the collector coil's circumference. The frequencies are directly related to the circumference of the collector coil.

from that, SM doesn't really clarify what that relation is. By directly he could have meant many things.

if there are 3 freq .. how are they each related to each other? .. by "relation" i was under the impression he was talking about harmonics. maybe related to the ratio of pi.

C/d = Pi
in radians, a circle is (2pi)=6.283185 rad .. where angular freq is 6.283 rad/s ?

could it be 2(Pi)f=v/r
    f is the frequency (measured in hertz),
    v is the tangential velocity of a point about the axis of rotation (measured in metres per second),
    r is the radius of rotation (measured in metres).

heck he could merely have been stating the obvious by referring to rotation of field per second.

@Jdo300 .. shouldnt the length of wire be related to the surface area???

Hey Wer,

Great synopsis on the frequencies! Sometimes it is the simplest explanations that we seem to overlook the most.

If I may reiterate a few points in support of what Wer is talking about. We know that the TPU is 'kinda sorta' like a transmitter and receiver all in one. We also know that it has qualities like a Tesla coil because of the disruptive discharges that take place in the coils.

Let me ask you all something, have you ever tried to drive a simple coil at its resonant frequency using a sine wave and then compare the same output when driven with a square wave? There is a difference. The output with the square wave can have an amplitude almost 50% larger than the same with the sine wave input. So there is definitely something going on with the abrupt pulses.

Perhaps the Earth electromagnetic field interaction is as simple as a tuned transmitter and receiver with the transmitter using square waves to amplify the power to the receiver.

Just more food for thought .

God Bless,

Hi devilzangel,

I believe that the area enclosed by the loop antenna only matters if it is operated to couple with the magnetic component of the input frequency. When operated in the electric mode, only the total length of wire that makes up the loop matters.

However, since we know that Mr. Mark puts DC on the collector, I believe it is safe to assume that the area the collector encloses is important.

Check out this site about magnetic loop antennas:

http://home.datacomm.ch/hb9abx/loop1-e.htm

According to this site, the diameter should be some fraction of the wavelength to receive:

The diameter of the loop is in the range of 1/10 to 1/100 of the wavelength.
The antenna works primarily with the magnetic component of the EM field, which extends to the both EM components on larger distance. For that reason the antenna operates well close to ground and radiates a much stronger signal than a dipole when both are close to ground.

Also interesting to note is the fact that loop antennas a very directional, which might explain why the TPU stops working when it is flipped over.

Ohh! Found some better info that explains the relation Mr. Mark was talking about. Check out the following quote from this other website I found here: http://www.qsl.net/mnqrp/Loop/Mag_Loops.htm.

The theory for calculating the loop is very simple.The circumference of a magnetic loop is 1/4 wave of the design frequency.

Example for 14 MHz.

       300 / 14 MHz = 21.428 m is 1 wave

       21.428 / 4   =  5.357  m is 1/4 wave circumference

      5.357 / 3.14  =  1.706 m diameter.

So for a 6 inch TPU:

Circumference = 18.85 in (0.478 m).
1/4 wavelength frequency = 156.645MHz

This is assuming a single turn collector and not taking into account capacitance/inductance and all that jazz...

Here is another website that talks about making VLF loop antennas, which is what we wanna go for (VLF is < 1MHz):

The trick is fitting it into a 6" or 15" TPU .
