      產品詳細介紹Product Introduction

      TW4022 Single Band GNSS Antenna (Pre-filtered)

      The TW4022 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 TW4022 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.

      The TW4022 includes a pre-filter designed to mitigate strong intermodulated or near frequency signals.

      Even with the wider bandwidth, the TW4022 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.
