TW3967 Embedded Triple Band GNSS Antenna with L-Band

The TW3967 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 Corrections coverage and is especially designed for precision triple frequency positioning. The TW3967 provides superior multipath 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.

The TW3967 features a precision tuned, twin circular dualfeed, stacked patch element. The signals from the two orthogonal feeds are combined in a hybrid combiner, amplified in a wideband 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 intermodulated signal interference from LTE and other cellular bands.

The TW3967 offers excellent axial ratio and a tightly grouped phase centre variation. The TW3967 covers from 1164 MHz to 1254 MHz and 1539 MHz to 1606 MHz.

The TW3967 is also available with 35 dB with part number TW3972E. A 100 mm ground plane is recommended.
