Yagi antennas are formed by a dipole, the reflectors and one or more directors. The dipole is the element that gather the broadcast electromagnetic energy (works as the sensor element) and has the appropriate dimensions to operate in the frequency band of the antenna. The reflector placed behind the dipole avoids the back reception of signals, reinforcing the frontal reception. The directors which are placed in front of the dipole narrow the beam or reception lobe of the antenna, increasing its gain and directivity. This way, the antenna can receive TV stations at longer distances while, increasing its directivity, blocking inference.
