Sector antenna working in 5 GHz band with 18 dBi gain vertical polarization. Because of reduced sidelobes, antenna keeps clear strong signal even in crowded radio enviroment. It´s resistant to interference from other networks and does not disrub to other. Antenna features no beam squint due to frequency change, it means that decreasing of data throughput or even loss of a link after frequency channel change does not occur. Perfectly designed for operation under severe weather conditions. A proper materials allow operation in the salt water environment without corrosion. Professional mounting system with 0-15 degrees scale guarantees easy and smooth tilt down as well as rock-stable operation.
