Description
The Hemisphere A45 Antenna is the antenna designed to support milimetre level accuracy for land and marine applications. The A52 is the antenna that is capable of standing up to the environments you need it to. The A52 antenna has been designed to be left outside and thrive in the elements. The Hemisphere A52 boasts an impressive IP69K environmental rating and a EP455 shock and vibration rating. No matter where you need this antenna, it will last for years. The A52 is built to last in salt, fog, and spray. There is no need to worry about it. With an aluminum body and plastic cap, this antenna will last you for years to come.
Just because the Hemisphere A45 Survey Grade Antenna is built to last does not mean any technology has been sacrificed. The A45 antenna is a multi-frequency, multi-constellation antenna. With access to GPS, GLONASS, Galileo, Beidou and SBAS, the A52 has the technology to work for years to come. With access to more constellations, you have the ability to get a more accurate position. With the capability to receive L5 corrections, Hemisphere’s A45 also performs well in high traffic environments. The triple frequency capability allows the antenna to perform better near buildings and under foliage as there is better multi-path mitigation compared to traditional dual frequency antennas.
