GNSS Surveying Antenna HX-CSX608A

  • The antenna part adopts the multi-feed design scheme to realize the coincidence of the phase center and the geometric center to minimize the influence of the antenna on the surveying deviation.
  • The high gain of antenna element and wide beam width provide the effect of receiving a signal with a low elevation angle, and can still receive the satellite normally in some cases with serious occlusion.
  • It can effectively reduce the influence of multipath on the surveying accuracy.
  • Waterproof and anti UV covers, increasing the reliability for long term field work of antennas.
