TW3972 Triple Band Antenna 三频GNSS天线 37dB
The TW3972 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 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. 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. 有预滤波
