      產品詳細介紹Product Introduction

      TW2920 Single Band Antenna with L-Band


      The TW2920 is an Accutenna® technology antenna that covers GPS-L1, GLONASS-G1, BeiDou B1, Galileo E1, SBAS (WAAS, EGNOS, GAGAN, & MSAS) and the downlink L-Band (1525– 1559MHz). The TW2920 provides superior multipath signal rejection, a linear phase response, and tight phase centre variation (PCV). This antenna is ideal for precision agriculture, autonomous vehicle tracking and guidance, and other applications where precision matters.

      The TW2920 features a dual-feed wideband patch element, plus a low-loss pre-filter followed by a three stage low-noise amplifier (LNA) including an additional mid-section SAW. This configuration provides excellent axial ratio across the full frequency band and strong protection against high-level subharmonic signals like LTE and near frequency signals such as WiFi.

      The TW2920 has a compact, robust, magnetic mount housing with a metal base and a UV resistant, tough wide temperature range plastic radome, and is available with a variety of connectors. The housing includes a screw down option, and is available with an adhesive attachment, without a magnet.

      The TW2920 is also available with an “armoured” cable. option, with the cable encased in tough corrugated conduit having a temperature range of-40 °C to +120C, excellent chemical resistance, stable bending, high cold impact strength, and UL94HB flammability standard compliant.
