The Tallysman TW1721/TW1722 is a compact wideband GNSS antenna that includes Tallyman’s Accutenna Technology which offers incredibly accurate circular reception for all upper L- band GPS, GLONASS, Beidou, and Galileo signals and associated augmentation signals. The TW1721/TW1722 is the right antenna for a range of applications, including avionics, law enforcement, military, precision agriculture, and construction.
Tallysman TW1721/1722 GNSS Antenna
The TW1721/TW1722 features a novel 25mm dual feed wideband patch element that, compared to competitors, provides a truly circularly polarized response, with a typical axial ratio of less than 2dB over the full bandwidth. This allows for a more linear carrier phase response and substantially improved multipath rejection for higher precision applications.
The TW1722 is the pre-filtered version of the TW1721. The pre-filter provides protection from strong near frequency or harmonic signals, such as LTE.
