Tallysman TW3887 Embedded Dual-Band GNSS Antenna
The TW3887 embedded dual-band GNSS antenna supports coverage for GPS/QZSS L1/L2, GLONASS G1/G2/G3, Galileo E1/E5b, BeiDou B1,B2, as well as SBAS (WAAS/EGNOS/MSAS).
Description
Overview
The TW3887 employs Tallysman’s unique Accutenna technology providing dual-band GPS L1/L2, GLONASS G1/G2 + BeiDou B1/B2 + Galileo E1 coverage and is especially designed for precision dual-frequency positioning.
The TW3887 features 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 TW3887 has a pre-filter which increases the antenna’s immunity to high amplitude signals, such as LTE and other cellular signals. The TW3887 offers excellent axial ratio and a tightly grouped phase center variation.
The TW3887 covers GPS L2 (1227.6 MHz), GLONASS G2 (1248 MHz centre), GPS L1/WAAS/EGNOS/MSAS (1575.42 MHz), GLONASS G1 (1602 MHz, centre), BeiDou B1/B2 (1575 and 1207 MHz) and Galileo E1 (1561 and 1589 MHz).
The antenna is supplied with a standard 60 mm diameter 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.
