L1/L2 Survey Antenna

This antenna supports receiving of seven frequency bands of  GPS, GLONASS, BDS satellite navigation systems   and meets the demands of measuring equipment for multiple system compatibility and high precision measurement.

It can be widely used in land surveying, marine surveying and channel measurement, earthquake monitoring, monitoring of landslides, bridges deformation monitoring, container terminal operations, and other occasions.

* Product applicable band´╝ÜGPS L1/L2 , GLONASS L1/L2, BDS B1/B2/B3
* Antenna structure is designed fully symmetrically, which can achieve the coincidence between the phase center and the geometric center, and improve the accuracy of the measurement
* High antenna gain.  Good direction of beam width. Good reception performance of low elevation navigation satellites.
* U
se of pre - and multi-stage filtering technology, effectively inhibits the strong interference with the signal, and improves the reliability of the system.
* Built-in lightning protection circuit and effective protection of the amplifier enable proper usage in the outdoor environment.
Built-in regulator circuit enables compatibility wide range of input voltage.
