      產品詳細介紹Product Introduction

      TW4039B Single Band GNSS Antenna (Pre-filtered)

       

      The TW4039 is very low power, compact GNSS antennas covering the GPS-L1, frequency band.

      This antenna features an LNA with pre- and post- filters to provide an overall “Brick-Wall” filter for protection against interference from 700 MHz, L-Band and near frequency LTE systems and also high-power transmitters below 1525 MHz.

      The TW4039B provides typical gain of 15 dB, with an excellent noise figure. It has 15 kV ESD circuit protection.  

      The LNA has a +/- 10 MHz bandwidth that covers the full GPSL1 signal plus the SBAS (WAAS /EGNOS/MSAS) frequency band (1572 to 1578 MHz).

      It is housed in a compact IP68 magnetic mount enclosure. The antenna can be ordered without the magnet. In such cases, the magnet is replaced with a plastic plug to provide a smooth under surface, with the option of ordering it with or without 1.1 mm thick doublesided VHB tape on the bottom. 
       

      Features:
      • Typical Gain: 16 dB
      • IP68 weatherproof housing
      • 70 dB rejection below 1525 MHz
      • 70 dB rejection above 1625 MHz
       

      Applications:

      • Battery operated monitoring
      • Covert Surveillance
      • Fleet management and asset tracking
      • Satcom based AVL solutions
