Tallysman SSL889XF Dual-Band Antennas are designed for precision dual frequency positioning where light weight is essential. These antennas incorporate a unique Accutenna technology that provides dual-band GPS L1/L2, GLONASS G1/G2/G3, Galileo E1/E5b, and BeiDou B1/B2b coverage. The SSL889XF antennas mitigate out-of-band signals and prevent GNSS antenna saturation. These dual-band antennas feature a precision-tuned, circular, dual-feed, stacked patch element. The SSL889XF antennas come with an IP67 rating and are REACH and RoHS compliant. Typical applications include precision GNSS positioning, precision land survey positioning, mission-critical GNSS timing, marine and avionics systems, and autonomous Unmanned Aerial Vehicles (UAVs).
