Swegeo TT225
GNSS Repeater
The TT225 is a compact GNSS signal repeater that integrates a low noise amplifier and filter for high-quality signal processing. It provides DC bias current for external GNSS antennas while simultaneously filtering and amplifying RF signals. The repeater ensures efficient signal relay by forwarding enhanced signals to additional antennas. With its small size, lightweight build, and flat frequency response, the TT225 is perfect for GNSS signal distribution and relay applications.
