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 and military applications the TW2710 and TW2712 provide a truly 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 and TW2712 provide the performance normally associated with 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 are available 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 plug that provides a smooth mounting surface.
