Overview

Like many of Tallysman’s_products, the TW2705 applies Accutenna technology. This antenna covers the BeiDou B1, Galilea E1, GLONASS L1, GPS L1 and SBAS (WAAS, QZSS, EGNOS & MSAS) frequency band (1557 to 1606 MHz). It is specifically designed for military, agricultural, and precision industrial OEM applications and features a dual-feed wideband patch element which as one LNA per feed, a final output gain stage, and a mid section Combiner and SAW filter.

This antenna produces exceptional multipath signal rejection due to the fact that it provides finely accurate circular response over its entire bandwidth and is available with custom cable lengths as well as a variety of connectors.
