GNSS antenna maker Tallysman has introduced the TW7875 magnetic mount GNSS antenna, which is designed for precision dual-frequency positioning. It is capable of receiving GPS L1/L5, GLONASS G1, BeiDou B1, Galileo E1/E5a and NavIC L5.

The TW7875 employs Tallysman’s Accutenna technology, which provides superior multipath signal rejection due to its low axial ratio across the full bandwidth, the company said.

The antenna also provides a linear phase response and tight phase center variation at a new economical price point, according to the company, which said it provides performance comparable to  higher priced dual-band GNSS antenna.

It is designed for precision agriculture, autonomous vehicles and other applications where precision matters.

The TW7875 is housed in a magnetic mount IP67 rated housing. It can also be ordered without the magnet since it can also be mounted by screws or double-sided adhesive tape.

Model TW3875 is the embedded antenna version of the TW7875. It is available with a wide selection of connectors and custom cable lengths, and can be custom tuned by Tallysman to ensure optimum performance within the customer’s enclosure.
