TW3876E Embedded Dual-Band GNSS Antenna

Tallysman TW3876E Embedded Dual Band GNSS Antenna

The TW3876E embedded dual band GNSS antenna from Tallysman supports coverage for GPS/QZSS L1/L5, GLONASS G1, Galileo E1/E6, BeiDou B1/B3, QZSS L6, as well as SBAS (WAAS/EGNOS/MSAS).



Ideal for precision positioning and RTK surveying systems, the TW3876E embedded dual band GNSS antenna from Tallysman provides excellent circular polarized signal reception, great multi-path and out-of-band signal rejection.

The TW3876E 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 TW3876E 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 TW3876E performs with excellent axial ratios and a tightly grouped phase center variation.

Tallysman offers custom tuning services to optimize the performance of the TW3887 for any OEM installation environment.
