Mounting kit for antenna and cable mountingMIMO antenna for LTE1800, UMTS2100, WiFi 2400, LTE2600. Gain 12-15 dB. For all operators. It is applied with 3G/4G modems and routers. Broadband (multi-band), directional, panel MIMO antenna KAA15-1700/2700 with a gain of 15 dB is recommended for use in conjunction with 3G/4G/YOTA modems, Wi-Fi routers and other equipment operating in the frequency range of 1700-2700 MHz. The antenna is designed to work in wireless communication networks with equipment of the following standards: 2G (EDGE, GPRS at GSM1800 frequencies); 3G (UMTS 2100); 4G (LTE 1800, LTE 2600), YOTA; WI-FI 2400 (IEEE 802.11b, g, n). The wide operating frequency range of the antenna allows 3G/4G/YOTA modems to work effectively at the boundaries of 4G service areas. The modem will automatically switch to the 3G standard in the absence of a 4G signal, and the antenna will provide it with a high-quality signal in both bands. High gain (15 dB) allows you to confidently work at a considerable distance from the base station of the mobile operator. The antenna works both for receiving and transmitting a signal. The use of MIMO technology allows you to increase the data transfer rate up to 150 Mbps. MIMO (Multiple Input Multiple Output) is a method of spatial signal coding that allows you to increase the channel bandwidth, in which systems of several antennas are used to transmit and receive data. MIMO technology is used in wireless communication systems (Wi-Fi, WiMAX, LTE) to increase bandwidth and more efficient use of the frequency band. The use of MIMO technology allows more data to be transmitted in one frequency range, thereby increasing the transmission rate. The antenna contains two radiating systems with orthogonal polarization, allowing you to work in the 2x2 MIMO mode. The sealed housing of the antenna is made of high-quality ABS plastic, resistant to UV radiation and atmospheric precipitation, which allows the antenna to be used both indoors and outdoors. The antenna inputs are short-circuited by direct current between the external and internal conductors, which reduces the likelihood of static electricity accumulation at the input of active equipment (modem, router). Thus, the probability of failure of the connected equipment (modem, router) from static electricity is reduced and the use of a lightning arrester becomes optional.
