TW3876E Embedded Dual-Band GNSS Antenna

The TW3876E is a precision-tuned dual-band Accutenna® technology antenna providing coverage for dual-band GPS/QZSSL1, QZSS-L6, GLONASS-G1, Galileo-E1/E6, and BeiDou-B1/B3, including the satellite-based augmentation system (SBAS) available in the region of operation [WAAS (North America), EGNOS (Europe), MSAS (Japan), or GAGAN (India)].

The antennas feature a precision tuned, circular dual-feed, 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 TW3876E has a strong pre-filter to mitigate inter-modulated signal interference from LTE and other cellular bands.

The TW3876E antenna offers excellent axial ratio and a tightly grouped phase centre.

This OEM antenna is supplied with a standard 60 mm (dia.)iameter circular ground plane, with a coaxial cable terminated with your choice of connector (right angle MCX is shown in the drawing).

Mounting holes are provided for attachment to larger ground planes. Custom tuning and ground plane options may be available, depending on purchase level commitment.
