TW7972 GPS L1/L2/L5, GLONASS G1/G2/G3, BeiDou B1/B2, Galileo E1/E5 plus L-band correction services coverage

The TW7972 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 TW7972 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. This antenna sets a new price/performance standard in its category.

The antenna also has a strong pre-filter to mitigate inter-modulated signal interference from LTE and other cellular bands.

Features

  • Accutenna® Technology
  • Tight Phase Center Variation (PCV)
  • Low noise LNA:  2.5dB typ.
  • Temperature compensating LNAs

Benefits

  • Superior multipath signal rejection
  • Ideal for RTK applications
  • Excellent signal-to-noise ratio
  • Consistent response in all operating
    temperatures

The TW7972 is housed in a magnetic mount (with pre-tapped screw holes), weather-proof enclosure for permanent installations. A 100 to 120mm ground plane is recommended.

This product is also available in an OEM format (TW3967 or TW3972E)

The TW7972 is IP67, REACH, and RoHS compliant.
