Tallysman TW8889 Dual Band GNSS Antenna

Ideal for dual frequency positioning where minimizing weight is important, the 52-gram TW8889 provides excellent axial ratio and tight Phase Center Variation (PCV). The TW8889 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 TW8889 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. This antenna is housed in an industrial-grade weather-proof enclosure that can be surface mounted via magnet, screws or adhesive material.
