Tallysman TW2710 Datasheet
TW2710/TW2712 Magnet Mount
Multi-Constellation Antenna
The TW2710/TW2712 by Tallysman Wireless
is a professional grade GNSS antenna 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 and offers
excellent axial ratio and circular polarized
signal reception, multipath rejection and out of
band signal rejection.
Dimensions (mm) p/n 32-2710-0
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.
Dimensions (mm) p/n 32-2710-7
The TW2710/TW1712 is housed in a compact,
industrial-grade weather-proof, magnet mount
enclosure, and comes with a variety of
connectors.
