Overview

Ideal for precision agriculture, autonomous vehicle tracking and guidance, and other applications where precision matters, the TW7875 dual band GNSS antenna provides excellent circular polarized signal reception, great multi-path and out-of-band signal rejection.

The TW7875 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 TW7875 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 TW7875 is housed in an industrial-grade weather-proof enclosure that can be surface mounted via magnet, screws or adhesive material.
