      產品詳細介紹Product Introduction

      TW4322 Single Band GNSS Antenna (Pre-filtered)

       

      The TW4322 is a wideband GNSS antenna covering the GPSL1, GLONASS-G1 and SBAS (WAAS, EGNOS & MSAS) frequency bands (1575 to 1606 MHz). It features a small patch element with 40% wider bandwidth than previously available in this format.

      Unlike its competitors, both GPS-L1 and GLONASS signals are included in the 1 dB received power bandwidth.

      The TW4322 has a two stage low-noise amplifier with a midsection SAW. A tight pre-filter is available in the TW4322 to protect against saturation by high-level subharmonics and LBand signals.

      Even with the wider bandwidth, the TW4322 antenna is the smallest high performance antennas 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.
