      TW2712 Single Band GNSS Antenna (Pre-filtered)


      The TW2712 employs Calian's patented Accutenna® technology covering the BeiDou B1, Galileo E1, GPS-L1, GLONASS-G1 and SBAS (WAAS, QZSS, EGNOS & MSAS) frequency band (1557 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 TW2712 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 TW2712 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 TW2712 has a pre-filter to provide extra protection against saturation by strong near frequency or harmonic signals, such as LTE.

      The TW2712 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.
