Calian TW Smart GNSS Antennas are multi-band antennas that use Accutenna™ technology and offer simultaneous multi-constellation GNSS reception. These antennas operate at a 5V to 36V over voltage protection range, WAAS, EGNOS, MSAS, and GAGAN + QZSS systems, and pre- and post-LNA filtering. The TW smart GNSS antennas come with industrial grade IP69K enclosure and are RoHS, REACH, and RED compliant. These are ideal for professional-grade applications such as precision timing, network synchronization, low current, and tracking/positioning.
