VGL1/L2HNRRKIT Technical Product Data Features • Roof Amplified Antenna Gain ≥ 35dB • Re-Radiating Amplifier with Power Supply Excellent Gain Flatness • Optional Mounting Kit Hardware Roof Antenna Mount & Re-Radiating Amp Mount • Variable Gain Re-Radiating Amp Gain Varies from –3 to +23 dB Description The GPS Variable Gain L1/L2 Hanger Re-Radiating Kit (VGL1/L2HNRRKIT) is a complete re-radiating system that allows re-radiation of the GPS L1 and L2 signals indoors. The VGL1/L2HNRRKIT consists of an active roof antenna, 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.
