A Tallysman Accutenna

TW3972 Triple Band GNSS Antenna + L-band Correction Services

The TW3972 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

TW3972 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 TW3972 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

TW3972 Dimensions (mm)

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 TW3972 offers excellent axial ratio and a tightly grouped

phase center variation.

The TW3972 covers from 1164MHz to 1254MHz and 1525MHz to

1606MHz.

The TW3972 is housed in a through-hole mount, weather-proof

enclosure for permanent installations. L Bracket or Pipe Mount

(part numbers 23-0040-0, 23-0065-0 respectively) are available

for non-rooftop installation.

A 100mm ground plane is

recommended for non-roof-top installations.

This product is also available in an OEM format (TW3967 for 28dB

and TW3972E for 35dB)
