The TW4721 is a compact, wideband Accutenna™ technology GNSS antenna that provides accurate reception for all upper L- band GPS, GLONASS, Beidou, and Galileo signals (L1, G1, B1, B1 BOC, B1-2, E1) and associated augmentation signals (WAAS, EGNOS and MSAS SBAS). It provides truly circular response over its entire bandwidth thereby producing superior multipath signal rejection resulting in higher accuracy of position and time.
The TW4721 is housed in a compact, magnetic or adhesive mount, IP67 compliant housing. The antenna can be ordered without the magnet. In such cases, the magnet is replaced with a plastic plug to provide a smooth under surface. A double sided tape can then be used to mount the antenna.
It is RoHS and REACH compliant.
