Beitian 3V-18V CORS RTK GNSS Survey Antenna High precision TNC-K, BT-147

Beitian CORS RTK GNSS Antenna  Product Introduction The BT-147 is a four-star multi-frequency satellite navigation antenna with high gain, miniaturization, high sensitivity, multi-system compatibility and high reliability, which can effectively meet the user's needs. Adopt multi-feed point design and fully symmetrical antenna structure, with very stable phase center, reduce antenna pair measurement error; The gain is high, the standing wave ratio is low, the receiving effect on the low elevation angle signal is obvious, and the star can be normally collected in the occasion where the blocking is serious; 3.equipped with anti-multi-path choke plate, with anti-surge design, can effectively suppress the out-of-band strong interference signal to ensure the reliability of the antenna; 4.using anti-UV PC material design, both beautiful and ensure that the antenna shell does not change color for a long time outdoor use, with IP67 waterproof rating, high temperature resistance, sun protectio
