Hemisphere A43 Antenna


The A43™ antenna and Eclipse™ GPS technology together provide superior multipath mitigation, stable phase centers and strong SNRs at any elevation. This antenna is adaptable to many different applications, and because it is mutli-frequency, it is sure to give you accurate positioning even in difficult surveying environments.

With Eclipse GPS technology, the Hemisphere GNSS’s A43 antenna will give you precision and value you can rely on. This antenna was made for countless different environments, including RTK positioning and navigation, precise guidance, construction survey and machine control applications.


The A43 antenna is also a multi-frequency, multi-constellation antenna (GPS, GLONASS, BeiDou, Galileo and SBAS), meaning it far surpasses dual-frequency (GPS and GLONASS) positioning, especially in challenging environments. With Eclipse GPS technology, you get strong SNRs even at low elevations, meaning you can trust the corrections you receive.


With its aluminum base, IP69K environmental rating and an EP455 shock and vibration rating, the A43 is built to last in difficult conditions. In addition, the A43 still performs in temperatures ranging from -40° C to +70° C.
