The TW8825 employs Tallysman’s unique Accutenna® technology, covering GPS/QZSS L1/L5, GLONASS G1, Galileo E1/E5, BeiDou B1/B2a, NavIC E5 as well as SBAS (WAAS/EGNOS/GAGAN/MSAS).

Ideal for dual frequency positioning where minimizing weight is important, the 52-gram TW8825 provides excellent axial ratio and tight Phase Centre Variation (PCV).

The TW8825 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 LNA, then band-split for narrow filtering in each band and further amplified prior to recombination at the output.

The TW8825 also includes an LNA pre-filter that provides enhanced protection against high level sub-harmonic signals like LTE and near frequency signals such as WiFi.

The TW8825 is housed in an industrial-grade weather-proof enclosure that can be surface mounted via magnet, screws or adhesive material.
