Basis passive detector

[mustefa ubram]

Is telescopic antenna in this scheme galvanic connected to RX circuit or its role here is only as metallic core of RX coil?

Telescopic antenna as the core for RX.Not connected to anything
dear freind What do you think?

I cannot see how telescopic antenna in such configuration can be effective. By changing its length you can rich small and not significant changes in inductance of coil depend of material of such antenna. But what can be goal of this apart from visual?

If antenna is connected to coil (probably cored by ferrite), then you can think about its polarization in regard to coil polarization. In your present design it is in opposite polarization to coil and target signal can be totally suppressed by coil. Visual such "space pistol" design rules, bot not electronically.

Hi All
According to me in the functioning of lrls we have an electric field that is detected by the telescopic antenna and this electric field is induced by the "phenomenon" that probably covers a wide range of frequencies. In the front end of lrls there is a sort of demodulator that modifies some parameters of the high gain amplifier. I may add that, according to me, the phenomenon exists even without sepolt metals, it is the compass/sky effect. A metal buried for a long time adds its own signature to the phenomenon, perhaps enhances or decreases a parameter. The operating frequency of the lrls has little importance because as I said the transformation or revelation of the phenomenon takes place at the input of lrls.

hi to all freinds
this is first video of first pd detector with passive detector and transmitter
I can reveal the gold ring of 10 cm.Is this true?
I do not know how to test.How do I use it in practice
, please advise?
MY FIRST VIDEO LINK

Hi Mustefa
As I have said on other occasions you need to have a place where you can make test, some target of gold or silver that must be buried for a month or more. A gold ring at 10cm does not mean anything. A lrl is not a metal detector. My lrl doesn't sense a coin at 1cm.

Hi dear Mustefa thanks brother.

Same who told you FrancoItaly. and

A lrl is not a metal detector

is Right I m totally Agree

Me too, present LRLs are Nothing Detectors.

If you wish to detect something, you still need a metal detector along with your dowsing rods (wooden or electronic)

tank you dear frenids
Can I use to get the proper frequency variable of signal Generator?And I change the frequency on the desired location?
I buried three months ago, two copper bowls.How can I test in this place?

[FrancoItaly]

You need to put in about 10m south of the target and then you have to get close, at some point the signal should increase or may decrease (depending on the type of LRL)

tank you franco
You think my pd can reveal copper with any frq?

[FrancoItaly]

Yes I think that the frequence isn't important.

tank you dear franco

[FrancoItaly]

A test that you can make is if with max sensitivity you sense the compass effect. If not I think that you have too low gain.

How Franco?

[FrancoItaly]

You must go in open air and turn your lrl around 360 degrees, with the compass effect you have a signal when you are near north or south direction.
