Small Base Station Antenna

Place of Origin: China

The small reference station antenna is a four-system full-frequency small choke antenna covering BDS, GPS, GLONASS, and GALILEO, which meets the requirements of current measurement equipment for high precision and multi-system compatibility. It can be widely used in high-precision occasions such as geodetic surveying and mapping, ocean surveying, waterway surveying, dredging surveying, earthquake monitoring, bridge deformation monitoring, landslide monitoring, and terminal container operations.

  • Application

1. The accuracy of the phase center reaches the millimeter level, and the phase center has high stability and good repeatability;

2. Using choke structure design to achieve excellent multi-path suppression effect;

3. The antenna has high gain at low elevation angles, and has strong tracking ability to low elevation angle satellites, ensuring that the number of available

 satellites in the system is sufficient;

4. The low noise amplifier has high gain, and the cable length can be more than 100 meters;

5. The unique waterproof and dustproof design ensures that the core components are completely sealed and can work normally outdoors for many years.
