TW7972 / TW3972
DOWNLOAD
The TW7972 and TW3972 are lightweight highprecision antennas supporting triple-band GPS/ QZSS-L1/L2/L5, GLONASS-G1/G2/G3, Galileo-E1/ E5a/E5b, BeiDou-B1/B2/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 correction services coverage, and are especially designed for precision triple-frequency positioning. TW7972 is magnetic mount and TW3972 is through hole mount.
These antennas provide superior multipath rejection and axial ratio, a linear phase response, and tight Phase Centre Variation (PCV), while protecting against intermodulation and saturation caused by high-level LTE 700 Mhz signals.
These antennas are ideal for precision agriculture, autonomous vehicle tracking and guidance, and other applications where precision matters.
