Datasheet
## TW8829 ## Multi-Constellation Dual-Band Antenna **Frequency Coverage:** GPS L1, L2 | GALILEO E1 | BEIDOU B1 | GLONASS G1, G2 The TW8829 employs Calian's patented Accutenna® technology providing dual-band GPS-L1/L2, GLONASSG1/G2, Galileo E1, and BeiDou B1 coverage and is especially designed for precision dual frequency positioning where light weight is important. The TW8829 features a precision tuned, circular dualfeed, 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 TW8829 offers excellent axial ratio and a tightly grouped phase centre variation. The TW8829 has a pre-filter which increases the antenna’s immunity to high-amplitude interfering signals, such as LTE and other cellular signals. A 100 mm diamter ground plane is recommended for optimal antenna performance. ## Applications - Autonomous unmanned aerial vehicles (UAVs) - Precision GPS position - Dual-frequency RTK receivers - Mission Critical GPS Timing - Safety & security - Network timing & synchronization ## Features - Very low noise preamp: 2.5 dB - Axial ratio: < 2.0 dB typ. - Tight phase centre variation - High-gain LNA: 26 dB typ. - Low current: 12 mA typ. - ESD circuit protection (15 kV) - Invariant performance from 2.5 to 16 VDC ## Benefits - Lightweight (52g excluding cable and connector) - Ideal for L1/L2 RTK surveying systems - Great multipath rejection - Increased system accuracy - Excellent signal-to-noise ratio - IP67, REACH, and RoHS compliant About Calian: With global headquarters and manufacturing in Ottawa, Canada, Calian is a leading manufacturer of highprecision antennas and components for Global Navigation Satellite System (GNSS) applications. Calian’s mission is to support the needs of a new generation of positioning systems by delivering unprecedented antenna precision at competitive prices.
