Overview

The TW3972 antenna uses Tallysman’s Accutenna technology to provide triple band GPS L1/L2/L5, GLONASS G1/G2/G3, BeiDou B1/B2, Galileo E1/E5a+b plus L-band correction services coverage. The TW3972 provides a range of benefits to the user, including multipath signal rejection, consistent response in all operating temperatures, and an excellent signal-to-noise ratio.

The antenna features a precision-tuned, twin circular dual feed, stacked patch element. The signals from both orthogonal feeds are merged 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 antenna also has a strong pre-filter to mitigate inter-modulated signal interference from LTE and other cellular bands.
