Two antenna outputs were used (out of 4 possible in the antenna). The PANEL 10 DUAL-BAND MU-MIMO 4x4 antenna was used in the test. Two work in vertical polarization and two in horizontal. It is worth noting the link parameters achieved and the date of installation. Proper installation of the mast, antenna and cable ensures stable and correct operation of the antenna installation.Īssemble the antenna bracket as shown in the picture.Ĭonnect the cable and insulate the antenna connector. The exact regulation of the antenna ensures proper propagation of radio signals. These numerous signals combine in the RX antenna and the receiver, resulting in signal summation, increasing bandwidth and reliability. This means that there may be more than one path that RF adopts when passing from the transmit (TX) antenna and the receiving (RX) antenna. Just as light and sound are reflected from objects, just like RF. This occurs in sites that have a large amount of metallic or other RF reflective surfaces. Multipath interference occurs when an RF signal has more than one path between a receiver and a transmitter. MIMO antenna systems are used to overcome a phenomenon known as multipath distortion or multipath interference.Ī diversity antenna system uses two or more identical antennas, located a small distance apart, to provide coverage to the same physical area. The back plate is powder coated and cured at high temperature, which ensures many years of trouble-free operation. The housing is made of ABS, which is resistant to impacts, and also resistant to many chemicals (acids, alkalis, salts) that may be found in industrial plants. It is intended for use in premises, warehouses, production plants. Low capacity does not blur digital signals and helps avoid the appearance of parasitic currents and reflections. It uses two polarizations at the same time - vertical and horizontal (2 radiators work in horizontal and two in vertical polarization). This ensures spatial multiplexing.ĭetails of which port works in what polarization can be found in the photo (after clicking on the main photo of the antenna, scrolling to the next photos) Specially designed arrays of radiators with a low internal capacity, guarantee correct operation with a high coding rate of 256 QAM and 1024 used in the upcoming wifi 7. Offering excellent use of both of these bands. The antenna works in two frequency bands simultaneously (2.4 and 5 GHz), on each of the four ports.
