Outside GSM/GPRS antennas. Description
GSM antennas manufactured by NPP DONKONT LLC will provide reliable communication for any GSM device, as well as stable operation of GPS/GLONASS trackers. Donkont antennas are designed and manufactured in Russia and have proven themselves as a reliable product with stable technical indicators and high quality. For many years, Donkont antennas have been successfully used at industrial facilities in harsh operating conditions. Recommended for use in industrial GSM communication transceiver modules, amateur radio structures, and, in some conditions, as an external antenna for GPS/GLONASS trackers with a cable length of up to 1 meter.
Low-loss radio cable is used in the production of the antenna, which allows for reliable communication even when using a long line (up to 10 meters). This quality of antennas allows them to be installed on equipment installed in lowlands or radio-opaque boxes with the antennas being moved into the line-of-sight zone of the receiving and transmitting station.
The declared technical characteristics of the antennas are confirmed by the experience of their practical application in automated control systems for equipment for electrochemical (cathodic) protection of underground steel pipelines from corrosion. The length of the antenna cable, in the basic configuration, is 3 meters and can be increased to 10 meters without significant reduction in characteristics.
