Description
The GPS Hangar Networked Re-Radiating Kit (L1/L2GHNRRKIT) comes with the components tobuild a re-radiating system that can re-radiate all the major GNSS frequencies indoors. The GNSSsignals received by the roof antenna are amplified and re-radiated to GPS receivers indoors,eliminating the need to attach receivers directly to the roof antenna. The L1/L2GHNRRKIT consists ofan active roof antenna, a passive re-radiating antenna, and a re-radiating amplifier(L1/L2GHNRRKAMP) with an external power supply that powers the entire system. A cable from theroof antenna to the re-radiating kit is required and can be purchased separately. With up to 150ft of
LMR400 low loss coax cable connecting the roof antenna to the re-radiating amplifier, theL1/L2GHNRRKIT will transmit GNSS signals indoors to receivers up to 100 feet away.
In the standard Networked (Externally Powered) configuration, the re-radiating amplifier output (J1)
is DC Blocked. 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.
