Hemisphere A45 Antenna

Description

The Hemisphere A45 Antenna is the antenna designed be in the elements, especially in marine applications. Boasting an impressive IP69K environmental and EP455 shock and vibration rating, the A45 is built for salt, spray and fog.

The Hemisphere A45 Survey Grade Antenna was not just designed to last; it was also designed for reliability and professional-level accuracy. The A45 antenna is a multi-frequency, multi-constellation antenna. With access to GPS, GLONASS, Galileo, Beidou and SBAS, and L5, you can get accurate positioning and performance in high traffic environments.
