Tallysman TW4721/TW4722 GNSS Antenna
Description
Overview
The TW4721/TW4722 GNSS wideband antenna wideband GNSS antenna provides incredibly accurate reception for all upper L- band GPS, GLONASS, Beidou, and Galileo signals, and associated augmentation signals. The TW4721/TW4722 uses Tallysman’s patented Accutenna technology. Compared to the competition, this antenna features an innovative 25mm dual feed wideband patch element that provides a truly circularly polarized response, with a typical axial ratio of less than 2dB over the full bandwidth. This means the TW4721/TW4722 offers a more linear carrier phase response and substantially improved multipath rejection for higher precision applications.
The TW4722 antenna is the pre-filtered version of the Tallysman TW1721. The pre-filter provides protection from near frequency or strong harmonic interfering signals.
