Tallysman TW1825 Accutenna® Embedded Dual Band GNSS Antenna

The Tallysman TW1825 is an OEM antenna ideal for dual frequency positioning where minimizing weight is essential. The 37-gram TW1825 embedded dual band GNSS antenna provides axial ratio and tight phase center variation (PCV). 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 TW1825 features a precision tuned, circular dual feed, stacked patch element.  The TW1825 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.
