Tallysman TW3882E Embedded Dual-Band GNSS Antenna
The TW3882E embedded GNSS antenna employs Tallysman's unique Accutenna® technology and is especially designed for precision dual-frequency positioning, providing dual-band GPS/QZSS-L1/L2, GLONASS-G1/G2/G3, Galileo-E1/E5a, and BeiDou-B1/B2 coverage, including the satellite-based augmentation system (SBAS) available in the region of operation [WAAS (North America), EGNOS (Europe), MSAS (Japan), or GAGAN (India)].
Description
Overview
The TW3882E embedded dual-band GNSS antenna is ideal for precision positioning PPP and RTK surveying systems, featured with excellent axial ratios and a tightly grouped phase center variation, and excellent circular polarized signal reception, as well as multipath and out-of-band signal rejection.
The TW3882E 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 TW3882E offers excellent axial ratio, a tightly grouped phase centre variation, in addition to a pre-filter that increases the antenna’s immunity to high amplitude signals, such as LTE and other cellular signals, and near frequency signals, such as WiFi.
The antenna is supplied with a standard 60 mm diameter circular ground plane, with a coaxial cable terminated with your choice of connector (The mechanical drawing shows a right-angle MCX connector). Mounting holes are provided for attachment to larger ground planes.
