      產品詳細介紹Product Introduction

      TW4029 Single Band GNSS Antenna (Pre-filtered)
       

      The TW4029 is a very low power, compact GNSS antenna covering the GPS-L1, frequency band. This antenna features an LNA with a nominal current consumption of just 2 mA, with constant performance from 2.5V to 16V supply voltage, and includes protection against close proximity L-Band transmitting antennas such as Iridium® and Globalstar™.

      The TW4029 has among the lowest power consumption available, yet still provides 21 dB nominal gain and an excellent Noise Figure.

      TW4029 patch has 40% wider bandwidth for better axial ratio and has 15 kV ESD circuit protection. The LNA has a +/- 10 MHz bandwidth that covers the full GPS-L1 signal plus the SBAS (WAAS /EGNOS/MSAS) frequency band (1572.5 to 1578 MHz). The TW4029 variant provides a “Brick-Wall” prefilter protects against saturation by high-level sub-harmonics and L-Band signals.

      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.
