Overview

The TW3972E is an Accutenna technology antenna providing triple band GPS L1/L2/L5, GLONASS G1/G2/G3, BeiDou B1/B2, Galileo E1/E5a+b plus L-Band correction services coverage and is especially designed for precision triple frequency positioning. The TW3972E provides superior multi-path signal rejection, a linear phase response, and tight Phase Centre Variation (PCV). This antenna is ideal for precision agriculture, autonomous vehicle tracking and guidance, and other applications where precision matters.

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.

The TW3972E offers excellent axial ratio and a tightly grouped phase center variation. The antenna also has a strong pre-filter to
mitigate inter-modulated signal interference from LTE and other cellular bands.

The TW3972E covers from 1164 MHz to 1254 MHz and 1525 MHz to 1606 MHz.

The OEM TW3972E is supplied with a standard 60 mm diameter circular ground plane, with a coaxial cable terminated with a connector (right angle MCX is shown in the drawing). Mounting holes are provided for attachment to larger ground planes. Custom tuning and ground plane options may be available, depending on purchase level commitment.

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