The L1/L2GPNRRKIT is a portable network re-radiating kit that comes standard with a plug-in Re-radiating amplifier and a re-radiating antenna. It does not include an active L1/L2 roof antenna.
The standard configuration does not provide source voltage to an active antenna but it may be specified. For Example: L1/L2PNRRKIT-N/110 is the standard configuration but it may also be ordered as an L1/L2PNRRKIT-N/110/5 which would send 5vdc to power an active antenna. The signal from the roof antenna is amplified and radiated out the Re-radiating antenna. If the GPS Receiver has line of sight with the Re-radiating antenna, it will receive the signal up to 100+ feet away.
