      產品詳細介紹Product Introduction

      TW8889 Dual Band GNSS Antenna

      The TW8889 employs Tallysman’s unique Accutenna® technology, covering GPS/QZSS L1/L2, GLONASS G1/G2/G3, Galileo E1/E5b, BeiDou B1/B2b, as well as SBAS (WAAS/EGNOS/GAGAN/MSAS).

      The TW8889 features a precision tuned, circular dualfeed, stacked patch element. The signals from the two orthogonal feeds are combined in a hybrid combiner, amplified in a wide-Band LNA, then band-split for narrow filtering in each band and further amplified prior to recombination at the output.

      The TW8889 offers excellent axial ratio and a tightly grouped phase centre variation.

      The TW8889 has a pre-filter which increases the antenna’s immunity to high-amplitude interfering signals, such as LTE and other cellular signals. A 100 mm diamter ground plane is recommended for optimal antenna performance.
