This GPS portable networked re-radiating kit is designed in places where an L1 antenna is already in place. The re-radiating kit receives an existing L1 signal and amplifies it then distributes the GPS signal indoors. The GPS re-radiating kit includes a passive antenna and amplifier with an external power supply for power the entire system. In the standard networked configuration, the re-radiating amplifier output port (J1) is DC blocked while the antenna port receives the RF signal and passes voltage back through to the antenna.
