A Tallysman Accutenna®
TW2710 / TW2712 Magnet Mount Multi-Constellation Antenna
The TW2710 / TW2712 employs Tallysman’s unique
Accutenna technology covering the BeiDou B1, Galileo E1,GPS L1, GLONASS L1 and SBAS (WAAS, QZSS, EGNOS &MSAS) frequency band (1557 to 1606 MHz). ). It isespecially designed for precision industrial, agriculturaland military applications. It provides truly circularresponse over its entire bandwidth thereby producing
superior multipath signal rejection.
The TW2710 / TW2712 has a low axial ratio, excellent
phase linear response and a tight phase centre variation,
providing the performance normally associated withhigher priced antennas.

Dimensions (mm)

The TW2710 /TW2712 features a dual-feed wideband
patch element, with one LNA per feed, a mid section
combiner and SAW filter, and a final output gain stage.
The TW2712 has a pre-filter to provide extra protection
against saturation by strong near frequency or harmonic
signals, such as LTE.
The TW2710 / TW2712 is housed in a compact,industrial-grade weather-proof, magnet mount enclosure,and is available with a variety of connectors and cable
lengths.

Dimensions (mm)The antenna can be ordered without the magnet. In suchcases, the magnet is replaced with a plastic plug toprovide a smooth under surface.

TW7872 Magnetic Mount Dual Band GNSS Antenna
The TW7872 is precision tuned dual band, Accutenna®
technology antenna for reception of GPS L1/L2, GLONASS
G1/G2, BeiDou B1, Galileo E1 and is especially designed for
precision dual frequency positioning. The TW7872 provides
superior multi-path rejection and axial ratio, a linear phase
response, and tight Phase Centre Variation (PCV), while
protecting against intermodulation and saturation caused byhigh level cellular 700MHz signals. This antenna is ideal for
precision agriculture, autonomous vehicle tracking andguidance, and other applications where precision matters.
The TW7872 features a precision tuned, twin circular dual feed,
stacked patch element. The signals from the two orthogonal
feeds are combined in a hybrid combiner, pre-filtered tominimize interference from out of band signals such as Cellular
LTE then amplified in a wide-band LNA and band-split for
additional filtering and amplification stages prior torecombination at the output.

TW7872 Dimensions (mm)

The TW7872 provides reception for signals in the bands
1213MHz to 1261MHz and 1557MHz to 1606MHz. It is housed
in a magnetic mount, weather-proof enclosure.
This product is also available in an OEM format (TW3867 for
28dB and TW3872E for 35dB)
