The vertical antennas A-8Z and A-11Z possess an increased gain (8 and 11 dBi), an ideally circular radiation pattern, small electrical tilt of the beam in a vertical plane. Their construction is formed by an antenna array with consequent feeding of the elements on the printed circuit board, implemented on the SHF material, which is characterized by a small value of the dielectric losses. The printed circuit boards are also plated by an SHF-lacquer, and the radome is encapsulated. The antennas are characterized by small sizes and reliable implementation.
