L’Lecher antenna is a fascinating and useful tool for capturing electromagnetic waves. It is widely used in different fields such as scientific research, geobiology and dowsing. In this article, we will discover the characteristics of these antennas, the criteria to take into account when purchasing them and the different possible applications.
What is a Lecher antenna?
A Lecher antenna is an antenna specially designed to measure electromagnetic frequencies. It is made up of two parallel metal bars, generally copper or brass, connected together by a loop. The distance between the bars can be adjusted, allowing a match between wavelength and frequency. Lecher antennas are often used to detect and measure electromagnetic waves in our environment, such as those emitted by electrical appliances, mobile phones or even Wi-Fi networks.
Criteria to take into account when purchasing a Lecher antenna
The quality of the material
The choice of material is essential to guarantee good conductivity and optimal reception of electromagnetic waves. Copper or brass Lecher antennas are the most common and offer excellent performance. It is also possible to find aluminum models, but these are generally less efficient.
Height and weight
The size and weight of the antenna should also be taken into account when purchasing. An antenna that is too heavy or bulky will be difficult to handle and could quickly tire the user. Choose an antenna that is light and easy to transport, especially if you plan to use it in different locations.
Graduations
Some Lecher antennas have graduations on the metal bars, making it easy to identify the measured frequencies. This feature is not essential, but can be useful for professional use or for people wishing to take precise measurements.
The price
The price of a Lecher antenna varies depending on its quality, materials and features. Count between 30 and 100 euros for a good quality antenna. Don’t hesitate to compare offers online and read user reviews to get an idea of value for money.
The different applications of the Lecher antenna
In scientific research
The Lecher antenna is a valuable tool for researchers working on electromagnetic waves, particularly in the field of physics and electromagnetism. It makes it possible to precisely measure the frequencies emitted by different devices or wave sources, as well as to study their behavior and interactions with various materials.
In geobiology
Geobiology is a discipline that studies the influence of electromagnetic waves on living beings and their environment. The Lecher antenna is used to detect geopathogenic zones (areas disturbed by harmful waves) in order to neutralize or avoid them. Geobiology professionals seek in particular to limit exposure to electromagnetic waves in homes and workplaces.
In dowsing
Dowsing is an esoteric practice consisting of capturing information using tools such as the pendulum, the bent stick or the Lecher antenna. The latter is often used to locate underground water sources, minerals, lost objects or even missing people. Although controversial, this practice has its followers and can be effective when carried out by experienced people.
How to use a Lecher antenna?
To correctly use a Lecher antenna, certain steps must be followed:
- Hold the antenna by the loop, without touching the metal bars.
- Stand in front of the object or area you want to analyze.
- Direct the metal bars toward the object or area in question.
- Slowly spread the bars until the antenna responds, such as oscillating or vibrating. This indicates that you have found an electromagnetic wave.
- Note the distance between the bars and refer to a look-up table to determine the measured frequency.
It is necessary to practice regularly to master this technique and obtain reliable results.
Make the right choice to buy a Lecher antenna
In summary, the purchase of a Lecher antenna should be guided by the quality of the material, the size and weight of the antenna, as well as its price. Also take into account any graduations on the metal bars if you are looking for increased precision in your measurements. Do not hesitate to consult user reviews and compare offers online to find the antenna that best suits your needs and your budget.
