Overview

Ideal for precision agriculture, autonomous vehicle tracking and guidance, and other applications where precision matters, the TW7872 dual band GNSS antenna from Tallysman provides excellent circular polarized signal reception, great multi-path and out-of-band signal rejection.

The TW7872 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 TW7872 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 TW7872 is housed in an industrial-grade weather-proof enclosure that can be surface mounted via magnet, screws or adhesive material.
