TW7882 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 TW7882 also includes an LNA pre-filter, providing enhanced protection against high level sub-harmonic signals like LTE and near frequency signals such as WiFi.

TW7882 is housed in an industrial-grade weather-proof enclosure that can be surface mounted via magnet, screws or adhesive material.
