Overview
The TW3990E 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 TW3990E 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. TheTW3990E 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, TheTW3990E provides superior multipath signal rejection, a linear phase response, and tight phase centre variation (PCV).
The TW3990E 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 TW3990E is supplied with a standard 60 mm diameter circular ground plane, with a coaxial cable terminated with a connector (right angle MCX is shown in the drawing). Mounting holes are provided for attachment to larger ground planes. Custom tuning and ground plane options may be available, depending on purchase level commitment.
This product is also available in a housed format: TW3990.
