Hemisphere A22 Outback S3
The A22 antenna is designed to help maintain tracking of GPS and differential correction signals in challenging environments. Sometimes keeping the antenna level and away from electrical noise is just not possible. With a metal base, lower profile, improved multi-path mitigation, and ability to filter out an additional 30 decibels of radio band frequencies, A22 offers superior noise rejection. The A22 is designed for use with Hemisphere GNSS Crescent® and Crescent Vector™ II receivers.
