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.

Tallysman‘s 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.

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