## A Tallysman _Accutenna[®]_ TW2710 / TW2712 Ma net Mount Multi-Constellation Antenna g 

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 has a low axial ratio, excellent phase linear response and a tight phase centre variation, providing the performance normally associated with higher priced antennas.

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.
