TW3972E Embedded Triple Band GNSS Antenna-with-l-band

Tallysman TW3972E Embedded Triple Band GNSS Antenna with L-Band

The TW3972E embedded triple band GNSS antenna from Tallysman supports coverage for GPS/QZSS L1/L2/L5, GLONASS G1/G2/G3, Galileo E1/E5a/E5b, BeiDou B1/B2, SBAS (WAAS/EGNOS/GAGAN/MSAS) and L-band correction services.



Ideal for precision agriculture, autonomous vehicle tracking and guidance, and other applications where precision matters, the TW3972E embedded triple band GNSS antenna with L-Band from Tallysman provides superior multi-path signal rejection, a linear phase response, excellent axial ratios, and tight Phase Centre Variation (PCV).

The TW3972E features a precision tuned, twin 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.

Providing enhanced protection against high level sub-harmonic signals like LTE and near frequency signals such as WiFi, the TW3972E provides these additional benefits with an LNA pre-filter.

Tallysman offers custom tuning services to optimize the performance of the TW3972E for any OEM installation environment.

This product is also available in a housed format: TW3972.
