Hemisphere’s A42 antenna is a multi-GNSS precision antenna. It ensures performance and accurate positioning for geodetic surveys, RTK positioning and navigation, precise guidance and machine control all because of its multi-constellation, multi-frequency design. With access to triple frequency (L5), and many constellations (GPS, GLONASS, Beidou, Galileo and SBAS) the A42 has improved multipath mitigation, allowing you to get corrections in environments you never thought possible.
In addition, because of its IP69K environmental rating, EP455 vibration rating, and 110° temperature range, you can take the A42 to places where traditional antennas would take a hit. The A42 antenna is also easy to mount and set up, because of its 5/8″ thread, and RF TNC connector.
