If you have special needs and purchase more quantity, you can contact us at any time. If you are very satisfied with our products, please give us 5 points. Thank you.
High quality industrial grade manufacturing, compatible with brand receiver, applied to high precision GNSS RTK receiver, antenna integrated 4G communication antenna, Bluetooth WIFI2.4G antenna and GNSS full frequency point antenna integrated design, receiving frequency coverage GNSS full frequency point. Multi antenna integrated design is convenient to integrate with GNSS receiver.
The antenna can be used with various satellite navigation receivers and is widely used in the fields of geodetic survey, navigation channel surveying, precision agriculture and SEA measurement. It also can be used in military field according to the application situation.
Product features:
1. The design of multiple feed points ensures the superposition of the phase center and geometric center.
The effect of measurement error can be reduced to a minimum
2. High gain and directional beam width of antenna elements to ensure receiving satellites
Performance of low elevation face mask
The internal resistance multipath effect plate can reduce the measurement error caused by multipath.
The measuring antenna is a high quality RTK antenna designed by integrated communication antenna. It can be widely used in land surveying, ocean surveying and other fields. Survey, channel survey, earthquake monitoring, bridge survey, container operation, etc.
