Tallysman TW3972EXF Embedded Extended-Filter Triple-Band GNSS Antenna + L-Band
The TW3972EXF from Tallysman is an embedded precision-tuned triple-band Accutenna® technology antenna providing coverage for triple-band GPS/QZSS-L1/L2/L5, GLONASS-G1/G2/G3, Galileo-E1/E5a/E5b, BeiDou-B1/B2/B2a, NavIC-L5, including the satellite-based augmentation system (SBAS) available in the region of operation [WAAS (North America), EGNOS (Europe), MSAS (Japan), or GAGAN (India)], plus L-Band correction services. The TW3972EXF is ideal for precision agriculture, autonomous vehicle tracking and guidance, and other applications where precision matters.
The TW3967XF 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, and band-split for narrow filtering in each band and further amplified prior to recombination at the output. The antenna also has a pre-filter to mitigate inter-modulated signal interference from Ligado, LTE and other cellular bands. The TW3967XF offers excellent axial ratio and a tightly grouped phase center variation.
