Nowadays, amateur radio can be, in extreme cases, one of the last remaining communication re- sources. Its worldwide relevance and number of followers increase daily, contributing to the creation of local amateur radio organizations. On the other hand, knowing how to design different kinds of amateur radio antennas is of great interest not only to the communities that make up such organizations, but also to those in the academic field, particularly as it concerns practical experience with communications systems, and in regard to emergency or disaster situations. This research shows the process to design an antenna prototype that can be made using easy-to find elements. Furthermore, it shows the trans- mission and reception tests carried out after the construction of the prototype, with the aim of conducting a spectrum analysis within a local setting. First, the text offers a brief explanation of the importance of amateur radio in communication; next, there is a description of the antenna type chosen and the methods applied to its construction; then, there is a comparative analysis of the different tests carried out at various transmission powers and at different distances in a local scenario.
