      產品詳細介紹Product Introduction

      TW3742 Single Band GNSS Antenna (Pre-filtered)

      The TW3742 is a precision high-gain GNSS antenna covering the BeiDou B1, Galileo E1, GPS-L1, GLONASSG1 and SBAS (WAAS, EGNOS, QZSS & MSAS) frequency band (1559 to 1606 MHz).

      It employs Calian's patented Accutenna® technology providing truly circular polarized signal reception through the entire bandwidth of the antenna, thereby providing superior multipath signal rejection. It is especially designed for precision timing, industrial, agricultural, military, and other precision applications.

      The TW3742 features a three 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.

      The TW3742 adds an additional pre-filter to provide extra strong protection from near frequency and strong harmonic signals.

      The TW3742 is housed in a permanent-mount metal base with two nickel coated nuts and a weatherproof enclosure. Two options for mounting are available: an Lbracket (P/N#23-0040-0) or a pipe mount (P/N#23- 0065-0).
       

      Applications:

      • High-accuracy & mission-critical global positioning
      • Timing applications
      • Precision agriculture, mining, and construction
      • Law enforcement and public safety
      • Avionics
      • Law enforcement and public safety
      • Fleet management and asset tracking
