The antenna of Lecher* is a rather recent dowsing rod.
There are several types and several forms of it (see picture), but all are based on the same physical principle.
The principle of Lecher's wire
This text comes from the booklet sold with the antenna, it is more an attempt of explanation that an absolute truth.
It highlights the sinusoidal way of the electrical current with bellies of tension and nodes of intensity.
Any metal conductor in the space constitutes an antenna which collects and emits at least half of what it collects.
The Lecher antenna corresponds to a closed line with the one of its ends. The position of the cursor will give a specific indication:
- in quarter of wave (phy/4) = parallel resonant circuit (or open)
- in half-wave (phy/2) = resonant circuit series (or short-circuit)
With a generator of Gigahertz, emitting in the centimetric waves, the correspondence on the antenna of Lecher can be checked. The centimetric scale of the antenna also makes it possible to appreciate harmonies with organic resonance in the electromagnetic spectrum.
The human body, thanks to the antenna of Lecher, is able to select information with the lower part of the electromagnetic background noise which does not allow the apparatuses measurements objectify subliminal.
Yes, good, but how do I use it ?
The most difficult part is to hold it, the marks is only one business of mental convention (see "Letter to Robin" in order to have an idea of what I'm talking about).
A booklet with a list of marks, corresponding to what it can find out, is provided with the antenna. You can read it on line here.
Here are two simple exercises, for beginners.
Exercise-example 1: Let's search the Magnetic-North
Take your compass, and place it in your pocket, without looking towards where it points.
Look on your list of value at Magnetic-North, it's written 5.7cm, therefore move the cursor of the antenna on the 5.7.
Concentrate (mentally) on the Magnetic-North then move in a circular way (clockwise) by holding the antenna in front of you (while turning on yourself) slowly.
When you will meet the axis of the Magnetic-North your antenna will become heavier, which will make it fall ahead (or behind,it can also vibrate according to your way of holding it).
Take a reference mark (a fix one), a tree, a piece of furniture...
To be sure that you didn't make an error, redo Step 2, 3 and 4, several times, and change direction (a blow in the clockwise sense, a blow in the opposite sense, until you will obtain the same reference mark each time.
Take your compass from your pocket (without moving of the place where was taken the reference mark, if not it is not valid any more!) and direct your compass in the direction of your reference mark.
If your compass shows the Magnetic-North: it's very good!
- Are you sure that your compass works ?
- Are you sure that the place where you are is electromagnetically neutral. Indeed if it is not, the compass will give you a false direction, perhaps you were right, start again the exercise in an other place.
- Among all the times where you have remakes Steps 2 and 3,there was one of the reference marks which was valid, you should be involved more, and try to feel well in your hands when the antenna is weighed down.
- If you have find the South magnetic, you're missing of concentration :-), but it's good.
Exercise-example 2: Searching the ley lines
Take a minimum of 2 great meters made of wood and your compass (2 meters each).
Look on your list of value at Hartmann, you can read 12.0cm (or 10.0cm), therefore move the cursor of the antenna on the 12.0.
Concentrate (mentally) on the Hartmann field then move in a side way by holding the antenna in front of you (walk like crabs), slowly.
According to the field that you're looking for, go perpendicular to its theoretical orientation (you also can walk while following the walls of the room where you are).
We will start by moving on the North-South axis.
When you cross the Hartmann's field your antenna will become heavier, it will make it fall ahead (or behind, it can also vibrate according to your way of holding it).
Take a reference mark (a fix one !), a chair, a tree...
To be certain not to make an error, redo Step 2, 3 and 4, several times, but by changing direction (right to left then left to right).
You should obtain a different result because the Hartmann's field (and others) has a strip of 21 cm so you have find the right side and the left side of it.
Place one of your meter in the center of the two reference marks obtained higher, and give him, using your compass, the North-South direction (or West-East).
Repeat Steps 2,3,4,5,6 by walking on the East-West axis.
Repeat Steps 2,3,4,5,6,7 to obtain a grid of meter, the crossing of two meters forms a node.
You should have something which looks like that.
- Are you sure that the place where you are is electromagnetically neutral. Indeed if it isn't the case the compass will give you false information, in this case it's possible that the network is deviated or cut, may be you're right, continue in an other place.
- If you find, that spacing between your meters does not correspond to the theoretical value (here 2.0 m North-South and East-West 2.50m), it's because certain spared apparatuses deform the network, however if you are outside in a forest, that can come from an electric cable or quite simply from under ground (see the accidents of relief).
