Product Description:
1. The antenna adopts multi-feed point design and completely symmetrical antenna structure, to realize the coincidence of the phase center and the geometric center,at the same time reducing
the influence of the antenna on the measurement error.
2, Adopt international advanced 3D structure choke design, equipped with anti-multi-path choke
plate, waterproof, anti-ultraviolet cover, with stable phase center, high positioning accuracy, good reception for low elevation signal, etc.
3. The low-noise amplifier adopts pre-filtering scheme to effectively suppress out-of-band interference and improve the reliability of the system.
4, The power supply circuit adopts lightning protection design, which can effectively protect the
low noise amplifier and ensure the antenna can still work normally in the harsh outdoor
environment.
5, Built-in voltage regulator circuit, the antenna can work normally in a wide input voltage range.
6. The radome material is made of special resin for satellite antenna. The surface of the radome
ensures salt spray resistance and corrosion resistance of ocean atmosphere, and it has no obvious
fading phenomenon in 5 years under intense sunlight ultraviolet radiation.
