The Calian TW164B Smart Power GNSS Splitter is a professional-grade device that allows a single GNSS antenna to feed up to four receivers. It supports a full range of satellite systems, including GPS/QZSS, GLONASS, BeiDou, Galileo, NavIC, and L-Band correction services. The antenna port is located on the front, with all four receiver ports arranged on the rear for easy installation.

Designed for high-availability applications in safety, security, timing, and infrastructure, the TW164B eliminates the single-point-of-failure problem found in earlier splitters, where the failure of a single powered receiver would disable all connected receivers. Its Smart Power design accepts power from all attached receivers, prioritizing Port #1 and switching automatically to the next available port if necessary, providing deterministic and fault-tolerant operation. In the event of an antenna failure, the splitter draws less than 1 mA per connector to indicate the fault without impacting other receivers.

The TW164B delivers best-in-class performance in noise figure, isolation, and linearity. It is housed in a robust, lightweight, corrosion-protected aluminum enclosure with IP67-rated waterproofing. Connector options include SMA female, TNC, or N-Type, and the splitter provides standard gain to compensate for splitting loss. Unused ports should be terminated with a 50 Ohm load to maintain optimal performance.
