TW7972 Triple-Band GNSS Antenna + L-Band

Tallysman Wireless' TW7972 provides superior multi-path rejection and axial ratio, a linear phase response, and tight phase center variation

Image of Tallysman Wireless' TW7972 Triple Band GNSS Antenna + L-BandTallysman Wireless' TW7972 is a precision-tuned triple-band Accutenna® technology antenna for reception of GPS L1/L2/L5, GLONASS G1/G2/G3, BeiDou B1/B2, and Galileo E1/E5a+b plus L-band corrections signals. The TW7972 provides superior multi-path rejection and axial ratio, a linear phase response, and tight phase center variation (PCV) while protecting against intermodulation and saturation caused by high level cellular 700 MHz signals. This antenna is ideal for precision agriculture, autonomous vehicle tracking and guidance, and other applications where precision matters. Architecturally, the TW7972 features a dual-feed circular stacked patch element. The signals from the two orthogonal feeds are summed in quadrature, pre-filtered in a low loss filter to protect against a wide range of potentially interfering signals, amplified in high linearity, wide-band LNA, then band-split, tightly filtered and amplified prior to signal recombination at the output. The TW7972 provides reception for signals in the bands 1164 MHz to 1254 MHz and 1525 MHz to 1606 MHz. It is housed in a magnetic mount, weatherproof enclosure. This product is also available in an OEM format (TW3967 for 28 dB and TW3972E for 35 dB).
