Calian TW16xB 1-4 Port Smart Power GNSS Signal Splitters
Calian TW164B and TW165B 1- to 4-Port Smart Power GNSS Signal Splitters are professional-grade full GNSS band signal splitters that connect one antenna to up to four receivers. These Calian signal splitters support GPS/QZSS-L1/L2/L5, QZSS-L6, GLONASS-G1/G2/G3, BeiDou-B1/B2/B2a/B3, GalileoE1/E5a/E5b/E6, NavIC-L5, and L-Band correction services. The TW164B and TW165B are available with either SMA, TNC, or type-N connectors. The TW164B offers standard gain to compensate for signal-splitting loss, while the TW165B offers 10dB gain over the splitting loss. Applications include GNSS signal distribution, GNSS receiver testing, and high-availability applications, as well as networking and infrastructure timing.
