      產品詳細介紹Product Introduction

      TW3152 Single Band GNSS Antenna (Pre-filtered)

       

      The TW3152 is a high-gain GPS antenna specifically designed for timing applications in high density cell / telecommunications tower applications where high levels of near-out-of-band interfering signals can be expected. This antenna featurs a 50 dB LNA gain to handle long cable runs often associated with installation on telecommunications towers.

      The TW3152 covers the GPS-L1 and SBAS (WAAS, EGNOS & MSAS) frequency band and employs Calian's patented Accutenna® technology to provide excellent cross polarization rejection and greatly enhanced multipath rejection.

      The TW3152 features a four (4) stage dual filtered LNA, while the TW3152 includes an additional SAW pre-filter to provide exceptional rejection of close out-of-band signals and additional protection against saturation by high-level subharmonic and L-Band signals.

      The TW3152 housing has a permanent-mount, IP69K compliant metal base, and an extended temperature range plastic radome, and is specifically designed to withstand the most challenging environmental conditions.
