The A21 single-frequency antenna from Hemisphere GNSS tracks GPS L1 signals and supports differential correction services such as SBAS and L-Band services. It provides excellent noise rejection and is capable of filtering out an additional 30 decibels of radio band frequencies. Furthermore, the A21 antenna offers enhanced multipath mitigation, which effectively reduces interferences caused by signals being reflected off surfaces such as trees, windows of buildings and ground.
The A21 antenna is specifically designed for Hemisphere GNSS Crescent and Crescent Vector II receivers.
