TW165 1-to-4 Port Smart Power GNSS Signal Splitter (10dB Gain)

Name: TW165 1-to-4 Port Smart Power GNSS Signal Splitter (10dB Gain)
Brand: Calian

Smart Power Splitter for Fault-Tolerant Performance in Critical Systems

Calian TW165 Signal Splitter is a professional-grade 1-to-4 port GNSS signal splitter designed to distribute full GNSS spectrum signals to up to four receivers. With 10 dB gain, it compensates for signal-splitting loss, ensuring high-performance GNSS reception. Featuring smart power switching for continuous operation, TW165 is housed in a rugged, IP67-compliant military-grade aluminum enclosure, making it ideal for safety-critical, timing, and infrastructure applications in harsh environments.
