Panel antenna working in 2.4 GHz frequency with 9 dBi gain. Can be mounted for horizontal or verticalpolarization. Antenna is built with very high quality materials, like a construction grade aluminium alloy, Uvinhibited ABS, stainless stell and zinc galvanized U-bolt. Because of reduced sidelobes, antenna keeps clear strongsignal even in crowded radio enviroment. It´s resistant to interference from other networks and does not disrupt toother. Designed for operation under severe weather conditions. A proper materials allow operation in the salt water environment without corrosion. Heavy-duty mounting elements guarantees an easy elevation adjust as well as rock-stable operation.
