This antenna is designed to include the full sweep of GNSS bands and frequencies including GPS (L1,L2,L5), GLONASS (G1,G2,G3), Galileo (E1, E5a, E5b,) BeiDou (B1C, B1I, B2a, B2b), IRNSS (L5), QZSS (L1,L2C,L5), SBAS and L-Band (1542MHz). Including the option for all these GNSS systems ensures quick time to first fix, enhanced navigational accuracy, and the reliability you expect from a Taoglas product. The dual-feed, dual-patch is designed for superb axial ratio, and the active electronics integrate low-loss filters and front-end SAW filters that help eliminate nearby out-of-band signals. High performance is achieved with a Gain figure of 26.8dB across bandwidth. The product is tested with a voltage rating range of 1.8 to 5.5 V for enhanced safety. ## Typical Applications : - Marine, Boats and Water Leisure Activities - Military Vehicle Tracking & Asset Tracking - Fleet Telematics and Navigation - Surveying and Mapping Systems ## Installation: The Neptune antenna was designed with a ruggedised IP67-rated enclosure and mount to cope with the most demanding marine environments and weather conditions. The white ASA material is lightweight and strong and the domed enclosure prevents water ingress and birds from resting on the antenna. The XAHP.30 allows for both pole and deck mounting options, and installation is simple. The antenna is designed to operate in conditions from -40C and +85C without any effects on performance. The antenna has a BNC(F) connector as standard and comes with a 5m RG-174 cable with BNC(M) connectors to connect you to your navigational equipment. Customised cable can be configured from the Taoglas Cable Builder if you require an alternative.
