Many people are sensitive to the atmosphere of a place or a house. They feel that something is good for them, touches them inwardly, is rough or stressful. The causes are usually fields and vibrations that cannot be measured by normal physics. In addition to the traditional dowsers and commuters who perceive these effects, a modern form of radiesthesia ('radiosensitivity') has developed which actually has its roots in physics. It uses an antenna that made it possible to determine the first wavelengths in physics. In trained hands, the 'Lecher Antenna' produces a precision and differentiation that far surpasses traditional radiesthesia and opens up profound answers. The advantages of this method and its practical
