Tallysman TW3967 GNSS Antenna

The Tallysman TW3967 antenna is versatile, durable, and provides a host of benefits to the user, including superior multipath signal rejection, consistent response in all operating temperatures, an impressive signal-to-noise ratio. The TW3967 is ideal for a range of applications, including precision GPS positioning, network timing and synchronization, mission-critical GPS timing.



Using Tallysman’s Accutenna technology, the TW3967 antenna provides triple band GPS L1/L2/L5, GLONASS G1/G2/G3, BeiDou B1/B2, Galileo E1/E5a+b plus L-band correction services coverage. The antenna features a precision-tuned, twin circular dual feed, stacked patch element. The signals from both 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.
