GPS ANTENNA SERIES
GPS Survey Antenna HX-GS481A Product Introduction 1. HX-GS481A is a GPS L1\L2、GLONASS L1\L2 dual band antenna, which can be used in land survey, marine survey, channel survey, seismic monitoring, bridge survey, container operation, etc. Technical Feature 2. Adopt multi feed design to ensure the superposition of phase center and geometrical center, and minimize the influence to measurement error. 3. Antenna element has high gain and wide beam width to ensure the signal receiving performance of satellite at low elevation angle. 4. Multi-path rejection board inside can eliminate the multi-path influence to measurement error. 5. Lightning proof circuit inside can protect the LNA from being damaged by surge immunity.
