Rtk Gnss GPS Beidou Quadrifilar Helix High Gain Active Dielectric Antenna U-Ggbg7151

Product Description

Product Description Features
1. Using multi feed point design to ensure the superposition of phase center and geometrical center which could minimize the influence of measurement error to lowest range
2. High gain of the antenna element and the direction map beam width to make sure the receiving satellites performance of low elevation mask
3. Resistance multipath effects board inside could reduce the measurement error caused by multipath
4. Water proof, shock proof and lightning resistance
Application
Survey antenna is the traditional RTK product standard antenna, can be widely used in land survey, marine survey, channel survey, seismic monitoring, bridge survey, container operation, etc.

Our Advantages The warranty period is 12 months. Within the 12 months, if there is any fault caused by non-artificial reason, which can be repaired by the customer themselves, we can offer the spare parts to the customer free of charge. If there is any problem which cannot be repaired by the customer themselves, the customer can resent the products to our factory for repairing free of charge, and the freight charge would be shared by the customer and our company two sides.Under the circumstances out of the warranty period, if there is any problem, we can repair free of charge for the customers, we just charge for the spare parts at the cost itself, and the freight charge would be bear by the customers.
If there is any problem caused by human reason within the first year, the service would be the same as the service out of thewarranty period. Company Profile
