      產品詳細介紹Product Introduction

      TW4020 Single Band GNSS Antenna 

       

      The TW4020 is a commercial grade wideband GNSS antenna covering the GPS-L1, frequency band. It features a small patch element with 40% wider bandwidth than typical GPS-L1 antennas.

      The TW4020 features a high performance custom tuned ceramic patch element, 15 kV ESD circuit protection, a highgain two-stage low-noise amplifier (LNA) with a mid-section high-rejection SAW filter. It covers the GPS-L1 and SBAS (WAAS/EGNOS/MSAS) frequency band (1572.5 to 1578 MHz), and it offers great circular polarized signal reception.

      Even with the wider bandwidth, the TW4020 antenna is among the smallest high performance antenna available.

      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.
