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 is especially
designed for precision industrial, agricultural
and military applications. It provides truly
circular response over its entire bandwidth
thereby producing superior multipath signal
rejection.
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.
An optional tight pre-filter is available, part
number TW2712 to protect against saturation
by high level sub-harmonics and L-Band
signals.
The TW2710/TW1712 is housed in a compact,
industrial-grade weather-proof, magnet mount
enclosure, and is available with a variety of
connectors.
