TW7972 Multi-band GNSS Antenna provides triple-band GPS coverage: L1 / L2 / L5, GLONASS G1 / G2 / G3, BeiDou B1 / B2, Galileo E1 / E5 and L-Band Correction Services, specially designed for Precision positioning in triple frequency.
The TW7972 provides superior multi-path rejection and axial ratio, a linear phase response, and tight Phase Centre Variation (PCV), while protecting against intermodulation and saturation caused by high level cellular 700MHz signals. This antenna is ideal for precision agriculture, autonomous vehicle tracking and guidance, and other applications where precision matters.

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 1164MHz to 1254MHz and 1525MHz to 1606MHz. It is housed in a weather-proof enclosure.
