Graflsoa BT-300 Multi-Frequency GNSS Antenna with TNC Connector, High Gain, Compact Design for GPS, GLONASS, BDS, GALILEO Systems

<ul><li>GOOD PERFORMANCE: The gain is high, the standing wave ratio is low, and the receiving effect on the low elevation angle signal is obvious, so the star can be normally collected in the occasion where the blocking is serious.</li><li>WIDE APPLICATION: This antenna covers the four-star multi-frequency external flying saucer antenna of GPS L1/L2 GLONASS L1/L2 BDS B1/B2/B3 GALILEO E1/E5b, which meets the needs of multi-system compatible and high-precision users of current GNSS measuring equipment. It is widely used in geodesy surveying, navigation surveying, navigation, precision agriculture and marine surveying. It can also be applied to the military field according to the application conditions.</li><li>RELIABILITY: Equipped with an anti-multi-path choke plate, with an anti-surge design, it can effectively suppress the out-of-band strong interference signal to ensure the reliability of the antenna.</li><li>HIGH PRECISION: Adopts multi-feed point design and fully symmetrical antenna structure, with very stable phase center, which can reduce antenna pair measurement error.</li><li>WATERPROOF: Using anti-UV PC material design can ensure that the antenna shell does not change color for a long time outdoor use, with IP67 waterproof rating, high-temperature resistance, sun protection and UV protection.</li></ul>
