The TW7976 is a precision-tuned Accutenna® technology antenna designed for precision positioning, covering the GPS/QZSS-L1/L2, QZSS-L6, GLONASS-G1/G2, Galileo-E1/E6, and BeiDou-B1/B3 frequency bands, including the satellite-based augmentation system (SBAS) available in the region of operation [WAAS (North America), EGNOS (Europe), MSAS (Japan), or GAGAN (India)], as well as L-Band correction services.
This antenna is ideal for Real-Time Kinematic (RTK) and Precise Point Positioning (PPP) applications, as well as precision agriculture, autonomous vehicle tracking and guidance, and other applications where precision matters.
The TW7976 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, wideband LNA, then band-split, tightly filtered, and amplified prior to signal recombination at the output.
This antenna provides superior multipath rejection and axial ratio, a linear phase response, and tight phase centre variation (PCV), while protecting against intermodulation and saturation caused by high-level LTE 700 MHz signals.
The TW7976 is housed in an IP67 weatherproof enclosure that supports direct screw, magnet, or adhesive tape attachment.
