fengchenda High-Precision Gps L1 L2 Rtk Gnss Antenna For Agricultural Surveying

Features:
* Brand new and high quality
* QT151 can receive GPS, for GLONASS, for Galileo, for Beidou and other frequency signals. The antenna has the characteristics of high gain, good low elevation gain, wide angle circular polarization, stable phase center, etc. It is suitable for four-, high-precision surveying and mapping, and is widely used in geodetic surveying, road construction, marine surveying, dock container operations and other occasions.
* The antenna part adopts a multi-feed point design to ensure that the phase center coincides with the geometric center, minimizing the of the antenna on the measurement error.
* The antenna unit has a high gain and beam width in the directional diagram, the reception effect of low elevation angle signals, and can still search for satellites normally in some severely blocked occasions.
* High and low temperature resistance, waterproof, and protection cover provide protection for the long-term of the antenna in the field.
