Ideal for train control sensors, autonomous vehicle tracking and guidance, precision agriculture, and other applications where precision matters, The TW3972 provides superior multipath signal rejection, a linear phase response, and tight phase centre variation (PCV).
The TW3972 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 LTE and other cellular bands. The TW3972 offers excellent axial ratio and a tightly grouped phase centre variation.
The TW3972 meets all requirements of the Association of American Railroads’ Electronics Environmental Requirements and System Management Standard (S9401.V1.0). In addition, it is also compliant with the EN45545-2, EN50121, EN50155, and EN61373 standards.
The TW3972 is housed in a through-hole mount, weather-proof enclosure for permanent installations. L-bracket or pipe mount (part numbers 23-0040-0, 23-0065-0 respectively) are available for non-rooftop installation. A 100 mm ground plane is recommended for non-roof-top installations. This product is also available in an OEM format (TW3967 for 28 dB and TW3972E for 35 dB).
Septentrio’s versatile and robust multi-frequency and multi-constellation receiver, designed for reference stations, provides the lowest noise measurement on the market while protecting and monitoring against multipath and environmental interference.
