TW3872 Dual-Band GNSS Antenna
Dual Band GNSS Antenna (Pre-Filtered)
The TW3872 Dual Band GNSS Antenna (Pre-Filtered) employs Tallysman’s patented Accutenna® technology providing dual-band GPS-L1/L2, GLONASS-G1/G2 + BeiDou B1 + Galileo E1 coverage and is especially designed for precision dual frequency positioning. The TW3872 features a precision tuned, circular dual-feed, stacked patch element.
The signals from the two orthogonal feeds are combined in a hybrid combiner, amplified in a wideband LNA, then band split for narrow filtering in each band and further amplified prior to recombination at the output.
