Using Tallysman’s unique Accutenna technology, the TW8829 GNSS antenna provides dual band GPS L1/L2, GLONASS G1/G2, Galileo E1, and BeiDou B1 coverage and is specifically designed for precision dual frequency positioning where light weight is an important factor. Featuring a precision-tuned circular dual feed, stacked patch element, the TW8829’s 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 also has a pre-filter which increases the antenna’s resistance to high amplitude interfering signals, such as LTE and other cellular signals.
