GPS Networking’s L1/L2GHNRRKIT is a complete re-radiating system that allows re-radiation of the GPS L1, L2, L5, Galileo, GLONASS and Omnistar signals indoors. It consists of an active roof antenna, a re-radiating amplifier with a wall mount plug-in transformer that powers the entire system, and a passive re-radiating antenna. The signal from the roof antenna is amplified and radiated indoors.
