The learning of phenomena related to electromagnetic waves develops in an evident way when students are stimulated significantly and, one of the possible ways are contextualized experimental practices. In this way, a system was developed that allows the sending and reception of electromagnetic waves, which can be provided by a signal generator or by a transmitting radio. For the implementation of the system, two Yagi-Uda antennas were built, intended for the transmission and reception of signals; for the emission of signals a low-power transmitter radio and for the measurement of the intensity of the received signals, a signal intensity meter was constructed from a multimeter in which a circuit was added that converts the signals received into direct current proportional to their intensity. The system was used in the physics discipline of high school, where it was observed that using this system, the students presented a better understanding of the phenomena related to electromagnetic waves.
