The mechanism of propagation of electromagnetic waves can be approached in different ways. Because all radio waves behave similarly in propagation space, predicting signal degradation due to hydrometeors, abnormal refraction, and the study of selective fading can be done on the basis of measurements from the measuring position. Although some older systems (e.g., microwave beams, propagation by ionospheric reflection) have less importance than new techniques (e.g., fiber-optic links, wireless systems), some systems have been developed to play a meaningful role in communication (e.g., digital television broadcasting via satellites). The part of results connected with noise increase due to precipitation, rain attenuation, and total signal degradation due to rain in the frequency range between 1 and 25 GHz, which were collected at the Kielce University of Technology, as a Polish member of COST Action IC0802 – Propagation Tools and Data for Integrated Telecommunication, Navigation, and Earth Observation Systems, is presented in this article.
