Features
■ The antenna part of the multi-point design and fully symmetrical antenna structure, phase center accuracy to millimeter level, and the phase center of high stability, good repeatability;
■ Using 3D multi-frequency choke coil design, to achieve excellent multi-path suppression effect;
■ The antenna low elevation gain, high altitude satellite signal tracking ability, to ensure that the system has enough number of satellites;
■ LNA part of the pre-filter design, effectively suppress the band interference signal, to avoid causing the amplifier saturation, improve system reliability;
■ Built-in lightning and voltage regulator circuit, the effective protection of the amplifier to ensure that the normal work in harsh environments;
■ Shell with high reliability of the engineering plastics, using the overall waterproof design, waterproof rating IP67, to ensure that the antenna can work outdoors for many years.
