Features
- Excellent Signal Reception: Re-radiating distance is around 3-5 meters from the Reradiator. In addition, full receiver visibility of GNSS L1/L5 satellites outdoor comes along with an amplified re-radiated signal indoor.
- Highly Integrated System: Designed to operate as a whole, the system kits are composed of a high-gain external GNSS L1/L5 antenna, a precisely calibrated amplifier circuit with a Patch type indoor Reradiator and a built-in power supply regulator that provides systems with power. The unit is designed as plug-n-play hardware and it can be installed either permanently to a secured location or quickly at users' convenience by using either screw mounting or glass suction cup, respectively, for the indoor reradiating active patch antenna.
- Efficiency & Convenience: The Reradiator transmits real time data throughout the vehicle directly to an unlimited number of users. Multiple GNSS L1/L5 receivers or hand-helds can share just one reradiating to receive timely data.
- Power Saving: Thanks to its GNSS L1/L5 Power Saver desgin, the system uses an independent power supply source, saving users from the need of other power source for their GNSS L1/L5 unit.
- Easy-to-Setup: No additional cables are required and no external GNSS L1/L5 antennas are needed to be plugged and unplugged when using a GNSS L1/L5 receiver inside the vehicle.

Configuration
Two Ports: RF input port and DC input port. a. RF input is connected to the active antenna (for GNSS L1 and L5 band). b. DC input is fed by USB DC voltage(typical is 5 voltage). c. RF input is amplified by at least 30 dB gain and then the amplified signal is radiated from patch antenna. d. The patch antenna is GNSS dual system for L1 and L5 band.
