HT-3D Choke Ring Antenna high accuracy survey antenna

HT-3D Choke Ring Antenna

3D choke antenna to meet the needs of highprecision measurement equip-ment and multisystem compatibility. Widely used in CORS stations set up, land surveying, seismic monitoring, monitoring of landslides, bridges and other high-precision measurement of deformation monitoring applications.

FEATURE

       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.
