Product description
The Roger GNSS-RAS-8 is an active 1-to-8 splitter that distributes the signal of one GNSS antenna to eight receivers. It is designed for GNSS time synchronization and signal distribution in server halls, laboratories and other facilities where reliable GNSS reception is required.
The splitter covers all GNSS constellations and the Iridium band within 1.15–1.63 GHz. The redundant power input keeps the signal on even if one power supply fails; the unit also works with a single power supply. The outputs are loaded with 200-ohm resistors, so the receivers do not raise false antenna alarms.
