      產品詳細介紹Product Introduction

      TW4721 Single Band GNSS Antenna 

       

      The TW4721 is a compact, wideband GNSS antenna that provides accurate reception for all upper L- band GPS, GLONASS, Beidou, and Galileo signals (L1, G1, B1, B1 BOC, B1-2, E1) and associated augmentation signals (WAAS, EGNOS and MSAS SBAS). This antenna employs Calian's patented Accutenna® technology.

      The TW4721 features a novel 25 mm diameter dual-feed wideband patch element that, in sharp contrast with its competitors, provides a truly circularly polarized response, with a typical axial ratio of less than 2 dB over the full bandwidth. This provides a more linear carrier phase response and substantially improved multipath rejection for higher precision applications.

      The TW4721 is the smallest, lightest, wideband GNSS antenna available. It is housing in a compact IP68 magnetic or adhesive mount enclosure and is available with a wide range of connector options and custom coax cable lengths. 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.
