GNSS-TW-3872-ANT, GPS L1/L2, Glonass G1/G2, Galileo E1 + BeiDou B1 antenna

• GPS L1/L2, GLONASS G1/G2 + BeiDou B1 + Galileo E1
• Gain 35dB, 32 dB min
• Temperature range -40°C to +85°C
• Weight 185 g
• Great multipath rejection and great signal to noise ratio

The GNSS-TW-3872-ANT employ Tallysman’s unique Accutenna technology providing dual band GPS L1/L2, GLONASS G1/G2 +
BeiDou B1 + Galileo E1 coverage and is especially designed for precision dual frequency positioning.

The GNSS-TW-3872-ANT features a precision tuned, circular dualfeed, stacked patch element. The signals from the two orthogonal
feeds are combined in a hybrid combiner, amplified in a wide-band LNA, then band-split for narrow filtering in each band and further
amplified prior to recombination at the output.

The GNSS-TW-3872-ANT offers excellent axial ratio and a tightly grouped phase center variation.

The GNSS-TW-W3872-ANT covers GPS L2 (1227.6MHz), GLONASS G2 (1248MHz centre), GPS L1/WAAS/EGNOS/MSAS (1575.42MHz),
GLONASS G1 (1602MHz, centre), BeiDou B1 and Galileo E1. (1561 and 1589 MHz). The GNSS-TW-3872-ANT has a pre-filter which increases the antenna’s immunity to high amplitude interfering signals, such as LTE and other cellular signals.
