HA32 UAV GNSS antenna
The A21 antenna is designed to maintain tracking of GPS, GLONASS, BeiDou, Galileo and differential correction signals in challenging environments. Sometimes it can be impossible to keep the antenna level away from electrical noise. A21 offers superior noise rejection with a metal base, lower profile, improved multipath rejection and the ability to filter out an additional 30 decibels of radio band frequencies. A21 offers excellent noise suppression. The A21 is designed for use with Hemisphere GNSS Crescent® and Crescent Vector™ II receivers.
