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
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 1164 MHz to 1254 MHz and 1525 MHz to 1606 MHz.
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 100 mm 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).
