The Vika-21F MIMO parabolic antenna is designed for use in a set of equipment for wireless data transmission systems of standards: 4G (LTE1800, LTE2600) 3G (UMTS 2100) 2G (GSM1800) WI-FI (IEEE 802.11b, g, n) and in other range systems 1700-2700 MHz. Vika-21F MIMO differs from Vika-21 MIMO in its input impedance (75 Ohm) and connector type (F-female) and the ability to use a budget TV cable. wireless internet. Antenna type - direct focus reflector antenna. To reduce the \"windage \" the reflector is made in the form of a cellular structure, the dimensions of the cell allow you to effectively reflect electromagnetic waves in all cellular communication ranges. The reflector has the shape of a circle and ensures the axisymmetry of the radiation pattern, the identity of the radiation patterns, the gain at both antenna inputs. For ease of transportation to the installation site, the antenna has a collapsible design: the mirror is assembled from eight segments. To increase rigidity, precision, lightness, and corrosion resistance, all segments are made of aluminum by injection molding. The design of the antenna feed uses solutions that have proven themselves in the popular UMO-3 MIMO feed, due to which, after setting the feed to the focus of the mirror, it is not required adjustment of the focal length depending on the frequency of the operator, since the phase center of the irradiator is almost the same for the entire operating frequency range of the antenna! Radiating elements are covered in a plastic case. The irradiator mount allows you to change the polarization angle without removing the antenna from the mast! On the spot! Without rotating the mirror! The antenna mount has a protective galvanized coating, aluminum parts (segments and feed holder) are powder coated. Advantages of the Vika-21F MIMO antenna: High gain in a wide frequency band Low windage due to the cellular structure of the reflector Collapsible design of the antenna and, as a result, small dimensions during transportation, the ability to send by mail No adjustment of the focal length is required when installing the antenna, when changing the operator, when changing frequencies ( standard) of the operator Provides the ability to adjust the angle of inclination of the polarization, the possibility of obtaining an additional gain in the most difficult reception conditions The presence of two emitting systems inside the irradiator with orthogonal polarization allows the modem to operate in MIMO 2x2 mode or use the capabilities of Diversity technology. Possibility of using budget: TV cable and F-connectors Active radiators of the antenna are covered in a plastic case Protective coatings on all metal parts Antenna inputs have a DC short circuit between the external and internal conductors, which allows you to protect the modem input from static electricity The mount allows you to mount the antenna on a vertical pipe, provision
