Hemisphere A43 Antenna

The A43 antenna delivers high performance even in tough environments due to it’s superior multipath mitigation and strong SNR’s.


The new A43™ antenna adds precision, reliability, and value to our leading Eclipse™ GPS technology. The A43 antenna is a multi-GNSS precision antenna and is ideal for various applications including construction surveys, RTK positioning and navigation, precise guidance, and machine control. Use the A43 antenna in challenging environments (such as near buildings and foliage) as it has superior multipath mitigation, stable phase center and strong SNR’s even at low elevations.

Hemisphere GNSS’s A43 antenna is the solution for those who want precision, value and most importantly reliability. With access to Eclipse GPS technology, the A43 is the total package. This is the antenna you can use for construction survey, RTK positioning and navigation, precise guidance and machine control applications.


The A43 antenna is also a multi-frequency, multi-constellation antenna. This allows the A43 to get positions in areas traditional dual freuency GPS, GLONASS antennas would simply not be able to do. With access to GPS, GLONASS, BeiDou, Galileo and SBAS, the A43 has access to the constellations that make getting an accurate position quicker and easier. This is the antenna that helps improve your chances of getting an accurate position. The multi-frequency support also means that the A43 performs exceedingly well even in challenging environments. In high traffic areas, such as those near buildings and heavy foliage, the A43 antenna has superior multi-path mitigation. This means that in spots other antennas would have a difficult, if not impossible time determining a position, the A43 is capable of providing a position. The Eclipse GPS technology also means that the antenna, even at low elevations has strong SNR’s, meaning you can always have a high degree of trust in the corrections you are receiving from the antenna.


The A43 is also the antenna that is built to last in difficult conditions. With an aluminum base and plastic cap, the A43 is built to last. In fact the A43 boasts an impressive IP69K environmental rating and an EP455 shock and vibration rating. This is the antenna that can perform in challenging conditions, and is meant to come out of them in one piece as well. On top of the ability to survive in just about any kind of condition, the A43 also performs in temperatures ranging from -40° C to +70° C. This is the antenna that sees you quit long before it will.
