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
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.
