Leo Store - Hemisphere GNSS - A21 & A31 Antenna 1

A21/A31 Antenna

 

 

The A21 antenna ensures reliable tracking of GPS, GLONASS, BeiDou, Galileo, and correction signals, even in tough conditions. Its metal base and lower profile provide superior noise reduction and multipath mitigation. With an added 30dB filter for radio frequencies, A21 excels in rejecting noise. Designed for Hemisphere GNSS Crescent and Crescent Vector II receivers. The A31 antenna similarly guarantees robust tracking of GPS, GLONASS, BeiDou, Galileo, Beacon, and corrections, with enhanced multipath mitigation and 30dB radio frequency filtering. Ideal for challenging environments and compatible with Hemisphere GNSS Crescent and Crescent Vector II receivers.
