The SBG-190 is a re-radiating antenna which relays the gps signal to provide a more reliable and accurate signal. The device picks up GOS signal and radiates it providing a better signal in built up area in the city or woodlands. A GPS satellite signal is reduced by as much as -125dBm by the time it penetrates the atmosphere and is received by a gps device. This is further compromised by scattering and reflection of the signal due to the presence of buildings in built up areas, which further impedes the performance of your GPS device, the re-radiating antenna is the ideal solution in such instances. The SBG-1290 containes a power regulated circuit with a high frequency low noise amplifier combined with a signal radiation device with an active outdoor antenna. SBG-190
