Description

 

The Variable Gain L1/L2 GPS Portable Re-Radiating Kit (VGL1/L2PNRRKIT) is a re-radiating system that allows re-radiation of the GPS L1 & L2 signals indoors. The VGL1/L2PNRRKIT consists of a re- radiating amplifier with variable gain, a wall mount plug-in transformer that powers the entire system and a passive L1/L2 re-radiating antenna.  The GPS L1 & L2 signal from the roof antenna is amplified, adjusted as necessary with the pot range control and radiated indoors.  Thus, if a receiver has line of sight with the re-radiating antenna, it can receive the GPS signal indoors up to 100 feet away.
