TW3972E Embedded Triple Band GNSS Antenna with L-Band

The TW3972E is an Accutenna® technology antenna providing tripleband GPS-L1/L2/L5, GLONASS-G1/G2/G3, BeiDou B1/B2b, Galileo E1/E5a/E5b plus L-band Corrections coverage and is especially designed for precision triple frequency positioning. The TW3972E provides superior multipath signal rejection, a linear phase response, and tight phase centre variation (PCV). This antenna is ideal for precision agriculture, autonomous vehicle tracking and guidance, and other applications where precision matters.

The TW3972E 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, then band-split for narrow filtering in each band and further amplified prior to recombination at the output.

The TW3972E offers excellent axial ratio and a tightly grouped phase centre variation. The antenna also has a strong pre-filter to mitigate inter-modulated signal interference from LTE and other cellular bands. The TW3972E covers from 1164 MHz to 1254 MHz and 1559 MHz to 1606MHz.

The OEM TW3972E is supplied with a standard 60 mm (dia.)iameter circular ground plane, with a coaxial cable terminated with a connector. Mounting holes are provided for attachment to larger ground planes. Custom tuning and ground plane options may be available, depending on purchase level commitment.
