Note : Your request will be directed to Tallysman Wireless.

The TW3972 from Tallysman is a triple band GNSS antenna that supports GPS/QZSS L1/L2/L5, GLONASS G1/G2/G3, Galileo E1/E5a/E5b, BeiDou B1/B2, SBAS (WAAS/EGNOS/GAGAN/MSAS), and L-band correction services. The antenna provides a gain of 37 dB and has an axial ratio of less than 2 dB. The TW3972 provides superior multi-path signal rejection, a linear phase response, and tight Phase Centre Variation (PCV).

This IP67 rated antenna features a precision-tuned, twin circular dual feed, stacked patch element. The signals from the two orthogonal feeds are combined by a hybrid combiner, amplified with 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.

This RoHS-compliant 66 x 21 mm antenna is housed in a through-hole mount, weather-proof enclosure for permanent installations. An L Bracket or Pipe Mount is available for non-rooftop installation. This L-band antenna is ideal for precision GPS positioning, triple frequency RTK receivers, military and security applications.
