TW7876 Dual Band GNSS Antenna

Tallysman TW7876 Dual Band GNSS Antenna

The TW7876 dual band GNSS antenna from Tallysman supports coverage for GPS/QZSS L1/L6, GLONASS G1, Galileo E1/E6, BeiDou B1/B6, as well as SBAS (WAAS/EGNOS/MSAS).



Ideal for precision agriculture, autonomous vehicle tracking and guidance, and other applications where precision matters, the TW7876 dual band GNSS antenna from Tallysman provides excellent circular polarized signal reception, great multi-path and out-of-band signal rejection.

The TW7876 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 wide-band Low Noise Amplifier (LNA), then band-split for narrow filtering in each band and further amplified prior to recombination at the output.

The TW7876 also includes an LNA pre-filter, providing enhanced protection against high level sub-harmonic signals like LTE and near frequency signals such as WiFi.

The TW7876 is housed in an industrial-grade weather-proof enclosure that can be surface mounted via magnet, screws or adhesive material.
