All about buying a Lecher antenna

I'Lecher's antenna is a fascinating and useful tool for capturing electromagnetic waves. It is widely used in various fields such as scientific research, geobiology or dowsing. In this article, we will discover the characteristics of these antennas, the criteria to take into account when buying them and the different possible applications.

What is a Lecher antenna?

A Lecher's antenna is an antenna specially designed to measure electromagnetic frequencies. It is made up of two parallel metal bars, usually copper or brass, connected together by a loop. The distance between the bars can be adjusted, making it possible to establish a correspondence between the wavelength and the 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 Wi-Fi networks.

Criteria to consider when buying 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.

The size and weight

The size and weight of the antenna should also be considered when purchasing. An antenna that is too heavy or bulky will be difficult to handle and can quickly tire its user. Choose an antenna that is light and easy to transport, especially if you plan to use it in different places.

Graduations

Some Lecher antennas have graduations on the metal bars, making it easy to identify the frequencies measured. This feature is not essential, but can be useful for professional use or for people who want to make precise measurements.

The price

The price of a Lecher antenna varies depending on its quality, materials and functionality. Count between 30 and 100 euros for a good quality antenna. Feel free to compare offers online and read user reviews to get an idea of the price-performance ratio.

The different applications of the Lecher antenna

In scientific research

The Lecher antenna is a valuable tool for researchers working on electromagnetic waves, especially 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 their 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 (zones 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 should be followed:

1. Hold the antenna by the loop, without touching the metal bars.
2. Stand in front of the object or area you wish to analyze.
3. Aim the metal bars at the object or area in question.
4. Slowly spread the bars apart until the antenna reacts, for example by oscillating or vibrating. This indicates that you have found an electromagnetic wave.
5. Note the distance between the bars and refer to a correspondence table to determine the measured frequency.

It is necessary to train regularly to master this technique and obtain reliable results.

Making 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 consider any graduations on the metal bars if you are looking for increased accuracy in your measurements. Feel free to read user reviews and compare offers online to find the antenna that best suits your needs and budget.
