      TW3892 Dual-Band Band GNSS Antenna + L-Band

       

      The TW3892 precision tuned duaL-Band, Accutenna® technology antenna for reception of GPS-L1/L2, GLONASS-G1/G2 + BeiDou B1 + Galileo E1+ L-Band coverage and is especially designed for precision dual frequency positioning.

      The TW3892 provides superior multipath rejection and axial ratio, a linear phase response, and tight phase centre variation (PCV), while protecting against intermodulation and saturation caused by high-level cellular 700 MHz signals. This antenna is ideal for precision agriculture, autonomous vehicle tracking and guidance, and other applications where precision matters.

      Architecturally, the TW3892 features a dual-feed circular stacked patch element. The signals from the two orthogonal feeds are summed in quadrature, pre-filtered in a low loss filter to protect against a wide range of potentially interfering signals, amplified in high linearity, wideband LNA, then band-split, tightly filtered and amplified prior to signal recombination at the output.

      The TW3892 covers GPS L2 (1227.6MHz), GLONASS G2 (1248MHz centre), GPS-L1/WAAS/EGNOS/MSAS (1575.42 MHz), GLONASS-G1 (1602 MHz, centre), BeiDou B1, Galileo E1. (1561 and 1589 MHz) and L-band Corrections (1539 to 1559MHz).

      The TW3892 is housed in a through-hole mount, weatherproof enclosure for permanent installations. L-Bracket or Pipe Mount (part numbers 23-0040-0, 23-0065-0 respectively) are available for non-rooftop installation. A 100 mm ground plane is provided for optimal performance.
