2D Base Station Antenna

Place of Origin: China

The 2D base station antenna adopts the traditional 2D choke coil design, and the product covers multiple frequency points. With multi-path suppression

technology, it can alleviate the impact of multi-path effects on measurement positioning accuracy, and can fully meet the applications in measurement,

aviation, reference stations, government, and mechanical control.

  • Parameters
  • Application

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

2. 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

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

4. Unique waterproof and dustproof design ensures that the core components are completely sealed and can work normally outdoors for

 many years
