Tallysman TW165 GNSS Splitter

The Tallysman TW165 is a professional-grade full GNSS band signal splitter that connects one antenna to four receivers, and supports GPS/QZSS-L1/L2/L5, QZSS-L6, BeiDou-B1/B2/B2a/B3, GLONASS-G1/G2/G3, Galileo-E1/E5a/E5b/E6, and L-band correction services.

The TW165 offers exceptional performance in terms of noise figure, isolation, and linearity. In addition, it is packaged in a corrosion-protected housing made of military-grade aluminum (6061-T6), which is robust, compact, and lightweight. The splitter has also passed the IP67 water ingression test.

The TW165 is available with either TNC or type-N connectors and offers 10 dB gain over signal-splitting loss.

Features

  • Accepts power from all attached receivers
  • Automatically switches on power failure of one receiver
  • Antenna failure detection/indication
  • Rugged military-grade aluminum enclosure
  • Amplification to compensate for signal-splitting loss
  • Very low noise figure
  • IP67-compliant

Benefits

  • Allows up to four GNSS receivers to share a single antenna
  • Fits in-line with antenna cable
  • Robust design
  • Suitable for harsh environments

The TW165 Smart Power GNSS signal splitter provides two key features:

First, it accepts power from all attached GNSS receivers and selects power from a receiver using the following protocol. Port #1 is given priority if its voltage is within the specified range (3.0 V – 12.5 V). However, if port #1’s receiver is disconnected or if its receiver power goes below the under-voltage or above the over-voltage specification, the TW165 will switch to the next port in numerical order, as long as its power and voltage are within the expected range. The switching and port selection is, therefore, deterministic.

Second, if the antenna fails and does not draw current, the TW165 will provide the receiver powering the antenna with a current draw lower than 2 mA, indicating an antenna fault.
