Description
The L1/L2G Portable Networked Re-Radiating Kit (L1/L2GPNRRKIT) is a re-radiating kit that isdesigned for deployments where a full L-band antenna is already in place. The L-band signal
received by the previously installed roof antenna is amplified and re-radiated to GPS receivers insideof a denied space using the passive re-radiating antenna. The L1/L2GPNRRKIT consists of apassive re-radiating antenna and a re-radiating amplifier (L1/L2GPNRRKAMP) with an external
power supply that powers the entire system. A cable from the roof antenna to the re-radiating kit isrequired and can be purchased separately.
In the standard Networked (Externally Powered) configuration, the re-radiating amplifier output (J1) isDC Blocked while the antenna port will receive the RF signal and pass the customer selected voltage(3.3 to 15 VDC). Custom gain, DC power, and connector configurations are available upon request.

Use Cases• To re-radiate signal indoors for GPS product testing.
• To maintain GPS signal for emergency vehicles parked indoors.
• To facilitate faster GPS signal acquisition for aircraft inside a hangar.
• In combination with one of our splitter devices, to create a GPS distribution network.
