Hemisphere A25 Antenna

Description

Hemisphere’s A25 Antenna is unlike any other for accuracy and reliability: A25 receives corrections from GPS, GLONASS, BeiDou, Galileo and SBAS. In addition, you can get strong SNRs even at low elevations.

The A25 Antenna can survive spray, fog, salt, vibration, shock, drastic temperatures, etc… The list goes on and on. Its IP69K environmental rating, EP455 vibration and shock rating both prove this.
