JMT Tri-Band 4G Cellular Signal Booster 2G 3G 4G Repeater 900+1800+2100Mhz GSM/DCS/WCDMA Signal Amplifier Precautions 1, Outdoor antenna installation location must be able to make a clear call (usually more than 3-4 grid is good) 2. Outdoor antenna and the host should be straight line distance of 7 meters, so as to avoid self-excitation. 3. The indoor antenna should be installed at a height of more than two meters on the indoor wall or upside down on the ceiling, and the outdoor antenna must be higher than the indoor antenna. 4. All connectors must be tightened and wrapped with tape to avoid water oxidation, resulting in reduced indoor signal coverage.
