Description
Hemisphere’s A25 Antenna is the antenna for those looking for more reliability and accuracy than traditional single frequency antennas. Unlike many other traditional single frequency antennas, the A25 receives corrections not only from GPS, but also GLONASS, BeiDou, Galileo and SBAS. This is the antenna that is capable of integrating multiple constellations when determine position, giving you a more reliable constellation. This is the antenna that will give you stronger SNR’s even at low elevations. This is the antenna that you can rely on to give you can accurate position even in challenging conditions. This is the antenna
The A25 Antenna is also built to last. With an IP69K environmental rating, this is the antenna that will last you for years to come. Whether you need to use this antenna on land or sea, this is the antenna that can withstand spray, fog and salt without any issues. On top of this, the antenna boasts a EP455 vibration and shock rating. This is the antenna that you can take to the places you need to work. There is no need to worry about this antenna falling apart on you. This is the antenna you buy for tomorrow, and for years into the future.
