The Tallysman TW165 Smart Power GNSS Splitter is a professional-grade solution designed for high-availability GNSS applications in safety, security, timing, and infrastructure systems. Traditional GNSS splitters relied on a single powered receiver, creating a single point of failure that could interrupt service if the receiver failed or was disconnected.

The TW165 overcomes this limitation with a Smart Power design that accepts input from all attached receivers. Port #1 is given priority if its voltage is within the specified range, and the splitter automatically switches to the next port if necessary, providing deterministic and uninterrupted operation. In the event of an antenna failure, the TW165 signals a fault by limiting current draw to less than 2 mA while maintaining operation for other connected receivers.

Delivering best-in-class performance in noise figure, isolation, and linearity, the TW165 is housed in a robust, corrosion-protected military-grade aluminum (6061-T6) enclosure that is compact, lightweight, and IP67-rated for water ingress protection. Connector options include TNC or type-N, and the splitter provides 10 dB gain over splitting loss, ensuring reliable signal distribution for multiple GNSS receivers in demanding environments.
