Tallysman TW3967XF Embedded Extended-Filter Triple-Band GNSS Antenna + L-Band
The TW3967XF 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 SBAS available in the region of operation [WAAS (North America), EGNOS (Europe), MSAS (Japan), or GAGAN (India)], plus L-Band correction services. It is designed for precision triple-frequency positioning.
The TW3967 is ideal for autonomous vehicle tracking and guidance, precision agriculture, and other applications where precision matters, The TW3967XF provides superior multipath signal rejection, a linear phase response, and tight phase center variation (PCV).
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 strong 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.
