These antennas are assigned for their operation within the compound of the base stations while the service zones are sectored. By means of thee antennas it is also possible to create a circular antenna array if the allocation of the antennas with the circular radiation pattern is prevented by the various superconstructions and the building walls. The antennas are characterized by an increased gain and the standard sectors of the radiation pattern what will allow to use the radio-waves` energy with the maximum efficiency.
In spite of the existing electrical tilt of the beam which positively influences upon the energy distribution of the irradiation in the near-field zone the mechanical tilt is also possible by means of the mechanism MN-1.
