TALYSMN~Tri-band + L-Band Fltr Pre-Filtered. Specify cable length and connector 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.
