A Tallysman Accutenna^®

TW2920 Wideband GPS/GLONASS/BeiDou/Galileo + L-Band Antenna

The TW2920 is an Accutenna technology antenna that

covers GPS L1, GLONASS G1, BeiDou B1, Galileo E1,

SBAS (WAAS, EGNOS, GAGAN, & MSAS) and the down-

link L-Band (1525 – 1559MHz). The TW2920 provides

superior multi-path signal rejection, a linear phase

response, and tight Phase Centre Variation (PCV). This

antenna is ideal for precision agriculture, autonomous

vehicle tracking and guidance, and other applications

Dimensions (mm)

where precision matters.

The TW2920 features a dual-feed wideband patch

element, plus a low-loss pre-filter followed by a three

stage Low Noise Amplifier (LNA) including an additional

mid-section SAW. This configuration provides excellent

axial ratio across the full frequency band and strong

protection against high level sub-harmonic signals like

LTE and near frequency signals such as WiFi.

The TW2920 has a compact, robust, magnetic mount

housing with a metal base and a UV resistant, tough

wide temperature range plastic radome, and is available

with a variety of connectors. The housing includes a

screw down option, and is available with an adhesive

attachment, without a magnet,

The TW2920 is also available with an “armoured” cable.

option, with the cable encased in tough corrugated

conduit having a temperature range of -40 to +120C,

excellent chemical resistance, stable bending, high cold

impact strength, and UL94HB flammability standard

compliant.
