      TW7972RXF Multi-Constellation Triple-Band Rugged Antenna


      The TW7972RXF is a surface-mount triple-band Accutenna® technology antenna providing coverage for GPS/QZSS-L1/L2/L5, GLONASS-G1/G2/G3, Galileo-E1/E5a/E5b, BeiDou-B1/B2a/B2b, NavIC-L5, and the satellite-based augmentation systems (SBAS) available in the region of operation [WAAS (North America), EGNOS (Europe), MSAS (Japan), or GAGAN (India)], plus L-Band correction services. It is especially designed for precision triple-frequency positioning.

      The radio frequency spectrum has become increasingly congested as new LTE bands are activated, and their signals or harmonic frequencies [e.g. 800 MHz × 2 =1600MHz(GLONASS-G1)] can interfere with GNSS antennas and receivers. In North America, planned Ligado signals at 1525–1536 MHz can especially impact GNSS antennas that support space-based L-Band correction services (1539–1559 MHz). New LTE signals in Europe [Band 32 (1452–1496 MHz)] and Japan [Bands 11 and 21 (1476–1511 MHz)] have also been observed to interfere with GNSS signals. In addition, Inmarsat satellite communication (uplink: 1626.5–1660.5 MHz) can affect GNSS performance. The new Tallysman XF antennas have been designed to mitigate out-of-band signals and prevent GNSS antenna saturation. Calian’s custom XF filtering suppresses all existing signals as well as the new Ligado and LTE signals, enabling the antennas and attached GNSS receivers to perform optimally.

      This antenna is ideal for precision agriculture, autonomous vehicle tracking and guidance, and other applications where precision matters. The TW7972RXF provides superior multipath signal rejection, a linear phase response, and tight phase centre variation (PCV).

      The TW7972RXF also provides excellent axial ratio, a linear phase response, and tight PCV, while protecting against intermodulation and saturation caused by high-level LTE 700 MHz signals. It is housed in a rugged, IP67 weatherproof enclosure and is available in magnetic, adhesive, and screw-mount configurations. A 100 mm diameter ground plane is recommended for optimal performance.

      Coverage:

      • Autonomous vehicle tracking and guidance
      • Positive Train Control (PTC)
      • Positive Train Location (PTL)
      • Precise GNSS positioning
      • Precision agriculture
      • Triple-frequency RTK and PPP receivers
      • Law enforcement and public safety
