Bueno para completar un poco decir que otra parte importante de la instalación es el cable, debe ser cable coaxial de 52 ohmios, buscar cables específicos para radio, no vale cualquier cable coaxial de antenia ni de tele ni de wifi, pongo una tabla donde se ven bien los ohmnios de cada cable, el más usado suele ser el RG-58.
