Description
This GPS re-radiating kit is designed for distributing GPS signals inside a hanger or large spaces without obstruction. GPS L1 signals is received by the include roof antenna, amplified, and then re-radiated indoors using the passive antenna. This hanger GPS re-radiating system consists of an active roof-top antenna, a passive re-radiating antenna, and amplifier with external power supply to power the entire system. In the standard network configuration, the amplifier output (J1) is DC blocked while the antenna port provides DC voltage to power the roof antenna.
Per the latest FCC guidance, the following use cases are NOT allowed:
- Fire Stations & First Responders
- Aircraft Repair and Maintenance
- Truck Repair and Maintenance
- Any other usages which could be considered "maintenance".
An FCC Experimental Broadcast license is required to operate this device, with the following exceptions:
- Device is operated in a shielded environment, such as an anechoic chamber.
- Device is operated in conjunction with a reradiating hood.
- Device is operated by federal or DoD personnel with the approval of the local spectrum manager.
Features
