The TW3885LXF is a precision-tuned dual-band Accutenna\u00ae technology antenna providing GPS\/QZSS-L1\/L5, GLONASS-G1\/G3, Galileo-E1\/E5a\/E5b, BeiDou-B1\/B2a\/B2, NavIC-L5 plus L-Band correction services, including the satellite-based augmentation system (SBAS) available in the region of operation [WAAS (North America), EGNOS (Europe), MSAS (Japan), or GAGAN (India)].<\/p>\n\n\n\n
Tallysman\u2019s eXtended Filter (XF) antenna technology has been designed to mitigate out-ofband signals and prevent GNSS antenna saturation. The radio frequency spectrum has become more congested as new LTE bands are activated and their signals or harmonic frequencies [e.g. 800MHz x 2 = 1600MHz (GLONASS-G1)] can affect 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 \u2013 1511 MHz)] have also been observed to interfere with GNSS signals. In addition, Inmarsat satellite communication (uplink: 1626.5 – 1660.5 MHz) can also affect GNSS signals.
Tallysman\u2019s custom XF filtering mitigates all existing signals and new Ligado and LTE signals, enabling the antennas and attached GNSS receivers to perform optimally.<\/p>\n\n\n\n
The TW3885LXF features a precision-tuned, twin circular dual-feed, stacked patch element. The signals from the two orthogonal feeds are combined in a hybrid combiner, amplified in a wideband LNA, then band-split for narrow filtering in each band and further amplified prior to recombination at the output. The TW3885LXF offers excellent axial ratio and a tightly grouped phase centre variation.<\/p>\n\n\n\n
Ideal for timing, autonomous vehicle tracking and guidance, precision agriculture, and other applications where precision matters, The TW3885LXF provides superior multipath signal rejection, a linear phase response, and tight phase centre variation (PCV).<\/p>\n\n\n\n
