Introduction
SBG-190 is are-radiating equipment. It can receive the outdoor GPS satellite signal and conduct to indoor place for radiating again. When a GPS Satellite is revolving around the earth it will transmit continuously satellite signal to the earth, but the strength of satellite signal will weaken to only around -125dBm when it arrived to the earth ground. Such weak signal can't penetrate into buildings or vehicles; besides, its reflection or scattering signal can be detected only in around windows area. SBG-190 is built for the purpose to transmit the GPS satellite signal from outdoor to indoor, and re-radiating the receptions for multi-user to operate GPS Receivers inside buildings or vehicles. SBG-190 contents a power regulation circuit, a high frequency low noise amplifier, a signal radiation set, and an active outdoor antenna to receive the GPS satellite signal.

Features
Plug-N-Play easy to use and improves your GPS signal strength
The re-radiating range could reach one meter diameter
The simple of structure makes for easy installation
For L1 band GPS signal, meets most of the GPS Receivers on the Market
This unit is not directly connected to your GPS unit, and can therefore be used with a variety of different models. It draws power from your car cigarette lighter. It is great for GPS without external antenna connector such as Garmin eTrex.
