The TW3972XF is a precision-tuned triple-band Accutenna® technology antenna providing coverage for triple-band GPS/QZSS-L1/L2/L5, GLONASS-G1/G2/G3, Galileo-E1/E5a/E5b, BeiDou-B1/B2b/B2a, NavIC-L5, including the satellite-based augmentation system (SBAS) available in the region of operation [WAAS (North America), EGNOS (Europe), MSAS (Japan), or GAGAN (India)], plus L-band Corrections. It is especially designed for precision triple-frequency positioning.

The TW3972XF 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 wideband 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 Ligado, LTE and other cellular bands. The TW3972XF offers an excellent axial ratio and a tightly grouped phase centre variation.

Ideal for train control sensors, autonomous vehicle tracking and guidance, precision agriculture, and other applications where precision matters, The TW3972XF provides superior multipath signal rejection, a linear phase response, and tight phase centre variation (PCV).

The TW3972XF meets all requirements of the Association of American Railroads’ (AAR) Electronics Environmental Requirements and System Management Standard (S-9401.V1.0). In addition, it is also compliant with the EN45545-2, EN50121, EN50155, and EN61373 standards.

The TW3972XF is housed in a through-hole mount, weatherproof enclosure for permanent installations. L-bracket (PN 23-0040-0) or pipe mount (PN 23-0065-0) are available. A 100mm ground plane is provided with the antenna, which ensures optimal antenna performance.

**This antenna is also available in an OEM format: TW3967XF (28 dB) and TW3972EXF (37 dB).
