Indoor GPS Re-radiating Kit

The HNRRKIT is a complete re-radiating system from GPS Networking that enables users to re-transmit the GPS L1 carrier signal indoors. The kit includes a roof antenna (38db Gain, 50 ohm), plug-in re-radiating amplifier, and re-radiating antenna. The re-radiating amplifier has a 110V/220V/240V plug-in transformer that powers the amplifier and the roof antenna. If a HNRRKIT user’s GPS receiver has line of sight with the re-radiating antenna, it will receive the signal up to 100 feet away, according to the company.
