Why use dual spiral sensor, not only one, or use of primitive telescopic antenna?

Here some scientifically based data in excerpt from Russian Physics Journal, Vol. 48, No. 9, 2005

In the present article, the design of a two-spiral flat coil intended for detecting NQR signals is described. Results of calculations of its magnetic fields and field non-uniformities are presented for windings of different types. It is demonstrated that the two-spiral coil field is localized in the near-field zone and has more uniform structure than the field of the conventional spiral coil with the same radius and winding type. It is emphasized that the two-spiral coil has higher sensitivity than the analogous conventional flat coil.

The description of methods of detecting 14N NQR signals with the use of a transceiving flat spiral coil can be found in [4–9]. In [7] windings of different types were analyzed and it was pointed out that the optimal winding for the spiral coil of a given diameter obeys the law
b = a ln(1 + k φ) ,
where b is the radial winding coordinate, φ is the current angle of the winding element in the polar system of coordinates, k is the coefficient determined by the coil dimension and the number of turns, and a is the logarithmic winding spacing.

On the other hand, the results of calculations demonstrate that the radio-frequency field of spiral coils is analogous to that of a single turn with current and radius equal to that of the coil. The denser the coil winding toward the external spiral radius, the closer the spiral winding field to that of the turn with current.As is well known (for example, see [12]), the coil with current has a wide effective directivity pattern; as a consequence, the spiral coil with the density of windings increasing toward the external coil radius will have low spatial selectivity and large noise level. The flat spiral coil with uniform winding [8, 11] has still a greater number of disadvantages than the coil with non-uniform winding.

At the same time, to increase the signal-to-noise ratio of the receiving antenna, the radio-frequency field of the coil must be localized in the volume being detected, and as already indicated above, a very uniform field must be created by the transmitting coil. In the present work, we suggest a two-spiral flat transceiving coil to improve the method and means for detecting NQR signals with flat spiral coils [8, 10]. The characteristics of this coil for a preset volume being detected are better than those of the conventional flat spiral coil with the same radius. We consider two-spiral flat coils of two types with constant winding spacing and spacing that obeys law (1) as well as give results of calculations of radio-frequency fields for coils of both types and of their average relative field non-uniformities together with measurements of NQR signal intensity with the two-spiral coils versus the distance from the examined sample.

Hi WM6,
After reading the Russian Physics Journal excerpt, I can see that the double spiral antenna (while an improvement over the single spiral), still has serious limitations in the signal to noise ratio. ie: The spiral coil must be localized in the volume of the RF field being detected, a very uniform field must be created by a transmitting coil.

Now, considering we are searching for gold, the dual spiral coil antenna will not be centered in a uniform gold RF field. Knowing that the gold signal is "shot in a signal line", a treasure hunter would have to be very lucky to be holding the antenna in the middle of this "shot signal" by chance. Therefore we can expect he will be getting a very poor signal to noise ratio with much random beeping until he gets lucky enough to cross into a gold signal line with the antenna. In addition, he will need to continually adjust the rotation, hoping to achieve proper phasing while searching for a gold signal line to position the antenna. I can see how treasure hunting could take some long time when using this dual spiral antenna.

For this reason I think it is of urgent importance to secure the design details for the advanced pyramidal logarithmic quadro spiral antenna. With the pyramidal logarithmic design, the reception will no longer be restricted to the limitations of law-1: b = a ln(1 + k φ) , and because it is a quadro design, the side-lobes of the gold signal are not lost as in the single and dual spiral designs. Is there any chance we will see some construction details for the pyramidal logarithmic quadro spiral antenna?

Best wishes,
J_P

Yes Fred, thank you. Of course we are speaking about 1730MHz on which natural gold resonate. For other frequencies this instructions are not valid.

Absolutely, except for all its harmonics and sub-harmonics (i think).
We could also measure amperage at coil ends, but for that we need Hung´s advice.

[WM6]

Hi wm6,

thanks...

please tell us more about building spiral antenna sensor and show in schematic where spiral antenna connect to board ?
also please give us exactly spiral antenna dimensions and it's material to detect gold?
if possible show detail of spiral antenna with picture...
I am waiting for your answer...

L1 and L2 (here only residue from first schematic with telescopic antenna) represent both spiral antennas. You simply replace L1 and L2 by spiral coils.

To build spiral antenna nothing is critical. But ideally for gold treasure you can follow this data:

- outer coil diameter 173mm
- number of turns 17,3 (because of centered beginning mean practically 17 full turns)
- material copper tube with hole not smaller than 1,73mm (copper wire diameter 1.73 mm on a supporting plate (see picture at post # 9) will also be good.)

Coil inductivity for gold have to be bigger than 173nH.

Not to forget to wind the coils in opposite direction, and to check correct winding and resonance that no conductivity must be measured between ends of a same coil. : as we all know when in resonance impedance of a coil raise sharply.

Yes Fred, thank you. Of course we are speaking about 1730MHz on which natural gold resonate (although we do not need to worry about resonance by spiral antenna because it is wide-band in contrary of telescopic antennas). For others metal this instructions are not adequate and need adoptions.

[Fred]

Not to forget to wind the coils in oposite direction, and to check correct winding and resonance that no conductivity must be measured between ends of a same coil. : as we all know when in resonnace impedence of a coil raise sharply.

Why dual spiral sensor? Scietifical view.

Why use dual spiral sensor, not only one, or use of primitive telescopic antenna?

hi wm6,

I want build this device (LRL) ...

You use chip INA121 for amplify receive signals...
I can use other preamps or other chip for this purpose ?
Did best antenna is spiral ?
How you tune this LRL to detect only gold signals ?

Good decision dear GOLDENSKULL, much better than buy other expensive LRL crap like mineoros, which cannot be tunned to gold but only to earth. What for tunning to earth? Only dr. Best Ultimate spiral sensor LRL can be tunned to gold, no other primitive telescopic antenna LRL solutions like mineoros.

And yes, build this LRL with spiral antenna is the best solution fo your homemade conditions. You can try both given schematic and make you sure.

Sorry, there is no known one chip replacement for INA121, therefore I recommend you ti find it and use. This is practically only critical part in schematics. Read this tread carefully.

Tunning to gold is only possible by dr. Best Ultimate dual spiral sensor. If we know that characteristic resonate frequency of natural gold is 1730MHz then we need to calculate wavelength from typical gold frequency which is 173mm. For distance between both spiral sensor coil we can use only multiple half-wavelength (mean 86,5mm) starting with multiplier 1x, the we can use 2x, 3x etc. half-wavelength. Half-wavelength because we have two spiral sensor and have to divide wavelength by 2. For fine tune one can borrow gold bar at the bank and tune by it dr. Best Ultimate LRL on gold at different half wave positions before the spiral front coil. Phase shift for ground effect elimination you can tune by rotating one of spiral coil sensor.

So all is logical (except circuit which is analog) and scientifically based.

Have you ever heard of the magic Golden number? Here you are: 173oMHz / 173mm - only by natural gold!!!!

The circuit you posted, no!!!

Hi Esteban,
You argue the circuit posted is not working. But you have never built this circuit for testing in the exact manner as Dr. Best. Maybe this circuit will not work with your FM radio version of LRL, but maybe works good with the spiral antenna for big improvements over the telescopic antennas.

Have you tested this circuit using the dual spiral antenna with advanced non-conductive wave guide and provisions to rotate for phase shifting as shown by WM6?
No?
Then how can you know it does not work?

Maybe it will be best if you first build the pyramidal logarithmic quadro spiral antenna, which is said to give best performance, and connect to the antenna this circuit with exact same components as shown. Then be careful to put shields on all nearby gold things. After testing with proper antenna, then you will have qualifications to determine if it works or not.

Best wishes,
J_P

[Esteban]

We made also LRL circuits...... but they don't work...

so maybe better making jokes... more funny!

Kind regards,
Max

Maybe you need more devotion!

[Esteban]

Dear Esteban, you start here argue that LRLs are not working. This is unbelievable. Are you ok?

The circuit you posted, no!!!

[Esteban]

This is true, this IC is an excellent choise.Seriously.


To Goldenskull: no, it´s only a joke.You won´t find a working schematic of a working LRL anywhere - and this is the best place on the world to look for.

Maybe soon, a demo version...?

[Fred]

Hi Esteban.
I believe that it is joke, but it is a good amplifier to replace the first stages of PCB5.....
Are you agree..... very good gain, hight slew rate
