Tallysman recognizes that the performance of a GNSS system is dependent upon the matched quality of all of its parts.  To this end, we have developed technology which provides superior performance in a multi-constellation environment.  Unlike traditional single feed patch antenna technology, Tallysman’s Accutenna technology is specifically designed to provide excellent multi-path signal rejection when receiving GPS L1, BeiDou B1, and Galileo E1 signals.

All of Tallysman’s antennas provide invariant response over the full range of operating voltages and operating temperatures.  They are available with a wide range of connectors and custom cable lengths.

Accutenna antennas appear in red below.
