      產品詳細介紹Product Introduction

      TW2408 Embedded Single Band GNSS Antenna (Pre-filtered)

      The TW2408 employs Calian's patented Accutenna® technology covering the GPS-L1, GLONASS-G1 and SBAS (WAAS, EGNOS & MSAS) frequency bands (1574 to 1606 MHz).

      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 TW2408 features a dual-feed wideband patch element, with a two stage low-noise amplifier, comprised of one input LNA per feed, a mid section SAW to filter the combined output, and a final output gain stage. This configuration provides excellent axial ratio that is constant across the full frequency band.

      The TW2408 comes in a compact circular form factor with a built-in 56 mm diameter ground plane.
