REQUEST PRICING

Overview

The TW1721 uses Tallysman’s wideband Accutenna™ technology for a truly circular reception of all upper L-band GNSS and SBAS signals. Superior multi-path signal rejection offers a higher accuracy of position and time. Using a dual feed wideband patch element, the TW1721 provides a uniquely circular polarized response, and with a typical axial ratio of less than 2dB over bandwidth, it improves multipath rejection for higher precision applications than its competitors.

With a built-in 35mm circular ground plane, the TW1721 is ideally augmented using a local system ground plane or reflecting surface.
