      產品詳細介紹Product Introduction

      TW2710 Single Band GNSS Antenna


      The TW2710 employs Calian's patented Accutenna® technology covering the BeiDou B1, Galileo E1, GPS-L1, GLONASS-G1 and SBAS (WAAS, QZSS, EGNOS & MSAS) frequency band (1559 to 1606 MHz). It is especially designed for precision industrial, agricultural, safety and security applications. It provides truly circular response over its entire bandwidth thereby producing superior multipath signal rejection.

      The TW2710 has a low axial ratio, excellent phase linear response and a tight phase centre variation, providing the performance normally associated with higher priced antennas.

      The TW2710 features a dual-feed wideband patch element, with one LNA per feed, a mid section combiner and SAW filter, and a final output gain stage. The TW2710 is housed in a compact, industrial-grade weatherproof, magnet mount enclosure, and is available with a variety of connectors and cable lengths.

      The antenna can be ordered without the magnet. In such cases, the magnet is replaced with a plastic plug to provide a smooth under surface.
