      產品詳細介紹Product Introduction

      TW3742 Single Band GNSS Antenna (Pre-filtered)

       

      The TW3372 is a high Gain (40 dB) GNSS antenna covering the GPS-L1, GLONASS-G1 and SBAS (WAAS, EGNOS & MSAS) frequency band (1574 to 1606 MHz).

      It features a patch element with 40% wider bandwidth than previously available in this format.

      Unlike its competitors, both GPS-L1 and GLONASS-G1 signals are included in the 1 dB received power bandwidth.

      The TW3372 has a three stage low-noise amplifier with a midsection SAW.  

      A tight pre-filter is available with the TW3372 to protect against saturation by high-level sub-harmonics and L-Band signals making it particularly suitable for timing applications.

      The TW3372 has a 19 mm(3/4 Inch) though hole, permanentmount white-metal base, with an industrial-grade, IP69K compliant conical radome with a North reference mark.

      Two options for pole mounting are available an L-bracket (P/N#23-0040-0) or a pipe mount (P/N#23-0065-0).

      Coverage:

      Features:
      • 40 dB LNA Gain
      • Pre-filter
      • Wide voltage input range (2.5 to 16 VDC)
      • IP69K Compliant conical radome with North reference mark)
      • Low Current (20 mA typ.)
       

      Applications:

      • Timing applications
      • Fixed installations
      • Cost-sensitive mission-critical global positioning
      • Law enforcement and public safety
