## TW3882 

## Multi-Constellation Dual-Band Antenna 

> **Frequency Coverage:** GPS L1, L2 | GALILEO E1, E5b | BEIDOU B1, B2b | GLONASS G1, G2, G3 

The TW3882 employs Calian's patented Accutenna® technology providing dual-band GPS-L1/L2, GLONASS-G1/G2 + BeiDou B1/B2b + Galileo E1 coverage and is especially designed for precision dual frequency positioning. 

The TW3882 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 TW3882 has a pre-filter which increases the antenna’s immunity to high amplitude signals, such as LTW and other cellular signals. The TW3882 offers excellent axial ratio and a tightly grouped phase centre variation. 

The TW3882 covers GPS L2 (1227.6MHz), GLONASS G2 (1248MHz 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 TW3882 is housed in a through-hole mount, weatherproof enclosure for permanent installations. L Bracket or Pipe Mount (part numbers 23-0040-0, 23-0065-0 respectively) are available for non-rooftop installation. A 100 mm ground plane is provided optimal performance. This product is also available in an OEM format (TW3887).
