TW2710/TW2712
TW2710 and TW2712 Single Band GNSS Antennas
Frequency Coverage: L1/G1/B1/E1
Overview
The TW2710 and TW2712 antennas employ Tallysman’s
unique Accutenna technology, covering the GPS L1,GLONASS G1, BeiDou B1, Galileo E1, frequency bands,
as well as SBAS (WAAS, QZSS, EGNOS & MSAS, 1557MHz
to 1606MHz).
Designed for precision industrial, agricultural andmilitary applications the TW2710 and TW2712 provide atruly circular response over its entire bandwidth thereby
producing superior multipath signal rejection.
With a low axial ratio, excellent phase linear response
and a tight phase centre variation, the TW2710 andTW2712 provide the performance normally associatedwith premium-priced antennas.
Each antenna also features a dual-feed wideband patch
element, with one Low Noise Amplifier (LNA) per feed, a
mid section combiner and SAW filter, and a final output
gain stage.
Differing from the TW2710, only by an added pre-filter
option, the TW2712 provides extra protection against
saturation by strong near frequency or harmonic
signals, such as LTE.
The TW2710 and TW2712 are housed in a compact,industrial-grade weatherproof enclosure, and areavailable with a variety of connectors and cable lengths.
They can be ordered with a choice of a magnet mount,adhesive mount, direct screw mount, or a plastic plugthat provides a smooth mounting surface.
