TW4721 Single-Band GNSS Antenna

Tallysman Wireless' TW4721 features a novel 25 mm dual-feed wideband patch element

Image of Tallysman Wireless' TW4721 Single Band GNSS AntennaThe TW4722 employs Tallysman’s unique Accutenna® technology, covering GPS/QZSS L1, GLONASS G1, Galileo E1, BeiDou B1, and SBAS (WAAS/EGNOS/MSAS). The TW4721 features a novel 25 mm dual-feed wideband patch element that provides a more linear carrier phase response by the axial ratio that is greatly improved across the full frequency bandwidth. 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. The TW4721 is housed in a compact IP67 compliant enclosure that can be surface mounted via magnet, screws, or adhesive material.
