Tallysman TW4721/TW4722 Wideband GNSS Antenna
TW4721/TW4722 is a Wideband Dual Feed GPS/GLONASS/BeiDou/Galileo Antenna
The Tallysman TW4721/Tw4721 is a compact, wideband GNSS antenna that provides accurate reception for all upper L- band GPS, GLONASS, Beidou, and Galileo signals (L1, G1, B1, B1 BOC, B12, E1) and associated augmentation signals (WAAS, EGNOS and MSAS SBAS). It offers circular response over its entire bandwidth, thereby producing superior multipath signal rejection resulting in higher accuracy of position and time. This antenna employs Tallysmans patented Accutenna™ technology.
The TW4722 is pre-filtered, the TW4721 is not. Please contact us for specifics.

The TW4721/Tw4722 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.
If you need enhanced protection against high level sub-harmonic signals like LTE and near frequency signals such as WiFi, select Pre-Filter for this product. If you have questions, contact us.
To minimize performance impact from signal jamming threats, the pre-filtered version of this antenna is compatible with Tallysman’s Anti-Jamming add-on, which modifies the radiation pattern of the GNSS antenna to eliminate signals arriving from -10° to +15° from horizon, while slightly increasing the gain of the antenna at zenith.
