Tallysman TW3882

Tallysman TW3882 GPS L1/L2 + GLONASS G1/G2 + BeiDou B1/B2 + Galileo E1 Antenna

The TW3882 employs Tallysman's unique Accutenna technology covering the GPS L1/L2, GLONASS G1/G2, Galileo E1, BeiDou B1/B2, and SBAS (WAAS, EGNOS & MSAS) frequency bands.



The TW3882 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 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 center variation.

The TW3882 covers GPS L2 (1227.6MHz), GLONASS G2 (1248MHz centre), GPS L1/WAAS/EGNOS/MSAS (1575.42MHz), GLONASS G1 (1602MHz, centre), BeiDou B1/B2 (1575 and 1207 MHz) and Galileo E1 (1561 and 1589 MHz).

The TW3882 is housed in a through-hole mount, weather-proof 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 recommended for non-roof-top installations.

This product is also available in an OEM format (TW3887).
