A Tallysman Accutenna^®

TW3967 Embedded Triple Band GNSS Antenna + L-band Correction Services

The TW3967 is an Accutenna^®technology antenna providing

triple band GPS L1/L2/L5, GLONASS G1/G2/G3, BeiDou B1/B2,

Galileo E1/E5 plus L-band correction services coverage and is

especially designed for precision triple frequency positioning.

The TW3967 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 TW3967 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 antenna also has a strong pre-filter to mitigate inter-

modulated signal interference from LTE and other cellular

bands.

The TW3967 offers excellent axial ratio and a tightly grouped

phase center variation.

The TW3967 covers from 1164MHz to 1254MHz and 1525MHz

to 1606MHz.

The TW3967 is also available with 35dB or 18dB gain with a

part number of TW3972E and TW3967LC respectively.

100mm ground plane is recommended.
