Description
The GPS Hangar Networked Re-Radiating Kit (HNRRKIT) provides the components required to builda GPS L1 re-radiating system which brings the GPS signal indoors. The GPS L1 signal received by
the roof antenna is amplified and re-radiated to GPS receivers indoors, eliminating the need to attach
receivers directly to the roof antenna. The HNRRKIT consists of an active roof antenna, a passive reradiating antenna, and a re-radiating amplifier (HNRRKAMP) with an external power supply thatpowers the entire system. A cable from the roof antenna to the re-radiating kit is required and can bepurchased separately. With up to 150ft of LMR400 low loss coax cable connecting the roof antenna tothe re-radiating amplifier, the HNRRKIT will transmit the GPS signal indoors to receivers up to 100
feet away.
In the standard Networked (Externally Powered) configuration, the re-radiating amplifier output (J1) isDC 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.
