Overview
The TW3990 is a precision-tuned full-band Accutenna® technology antenna providing full coverage of GPS/QZSS-L1/L2/L5/L6, GLONASS-G1/G2/G3, Galileo-E1/E5a/E5b/E6, BeiDou-B1/B2/B2a/B3, 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. It is specially designed for precise full-band GNSS positioning.
The TW3990 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 wide band LNA, then 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. TheTW3990 offers excellent axial ratio and a tightly grouped phase centre variation.
Ideal for train control sensors, autonomous vehicle tracking and guidance, precision agriculture, and other applications where precision matters, TheTW3990 provides superior multipath signal rejection, a linear phase response, and tight phase centre variation (PCV).
The TW3990 meets all requirements of the Association of American Railroads (AAR)’s Electronics Environmental Requirements and System Management Standard (S-9401.V1.0). In addition, it is also compliant with the EN45545-2, EN50121, EN50155, and EN61373 standards.
The TW3990 is housed in a through-hole mount, weatherproof (IP69K) enclosure for permanent installations. L-bracket (PN23-0040-0) or pipemount (PN23-0065-0) are available. A 100 mm ground plane is provided with the antenna, which ensures optimal performance.
This antenna is also available in an OEM format: TW3997 (28 dB) and TW3990E (35 dB).
