Directional parabolic JIROUS JRMB-900-10/11 antenna has been adapted to work with Mimosa B11 radio. The device has a narrow main beam with a width of 2.3°, allowing for a very efficient point-to-point connection. The time, allowing to avoid many interferences caused by other transmissions has a width of 900 mm and a gain of 37 dBi - it allows to obtain a connection even over long distances.
The antenna is created to work in harsh weather conditions and noisy environments. The cover made of UV-resistant ABS plastic is included. The parabola itself is made of aluminum so the impact of interference has been significantly reduced. JRMC-900-10/11 can be mounted on a pole with a diameter of 40 - 120 mm, handles are included in the kit.
