      產品詳細介紹Product Introduction

      TW2643A Single Band GNSS Antenna with Receive-Only Iridium

       

      The TW2643A employs Calian's patented Accutenna® technology in a magnet mount, active right hand circularly polarized antenna for the reception of all of the GNSS constellations (GPSL1/GLONASS-G1/ Galileo E1/ BeiDou B1) plus Iridum: 1559 to 1626.5 MHz frequency band. It is designed to ONLY receive the GNSS and Iridium signals (not transmit). This antenna is uniquely designed for indoor timing applications relying upon both GNSS and Iridium’s PNT signal.

      The TW2643A features a high performance dualfeed patch element that provides great axial ratio (4 dB max, < 2 dB @ zenith) over the entire Iridium® + upper GNSS frequency band, thus signals at the band edges remain truly circular, unlike the response of single-feed antennas.

      The TW2643A is housed in a compact, industrialgrade weatherproof, magnet mount enclosure, with threaded base holes for screw down attachment. 
       

      Features:
      • Custom high-gain, 5 dBic dual-feed patch
      • Great axial ratio, < 2 dB over full bandwidth
      • 15 kV ESD circuit protection
      • IP67 weather proof housing
      • Robust industrial-grade enclosure
      • Magnet or screw mount
       

      Applications:

      • Iridium® PNT applications+ GNSS
      • Timing (indoor and outdoor)
      • Fleet management and asset tracking
      • Marine & Avionics Systems
      • Law enforcement and public safety
