      產品詳細介紹Product Introduction

      TW2706 Embedded Single Band GNSS Antenna

      The TW2706 employs Tallysman’s unique Accutenna® technology, covering GPS/QZSS L1, GLONASS G1, Galileo E1, BeiDou B1, as well as SBAS (WAAS, QZSS, EGNOS & MSAS). It is especially designed for precision industrial, agricultural, safety and security OEM applications. It provides truly circular response over its entire bandwidth thereby producing superior multipath signal rejection.

      The TW2706 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 TW2706 is available with a variety of connectors and custom cable lengths. It is highly recommended to take advantage of Calian's custom tuning service to ensure optimal performance of this antenna in your housing and with your ground plane.
