JMT 4G Tri-Band Cellular Signal Booster 2G 3G 4G Repeater B1 B3 B5 Mobile Phone Amplifier 900 1800 2100mhz Precautions 1, Outdoor antenna installation location must be able to make a clear call (generally 3-4 more than the best grid) 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. Product detail: Frequency Band:900/1800/2100. Uplink: 890-915mhz, 1700-1779mhz, 1918-2000mhz. Downlink: 935-960mhz, 1796-1829mhz, 2096-2185mhz. Gain: Uplink 35 ± 3dB / Downlink 70 ± 3dB. Output Power: Uplink 17 ± 2dBm / Downlink 20 ± 2dBm. ALC Range: ≥15 IM3: ≤-36dBc VSWR: 2:1 Delay: ≤0.5us Impedance: 50 Ω Port: SMA.F Supply: 12V/2A Size HxWxD: 16.3*10.5*2cm Weight: 0.6KG Coverage: 0-2000 square meters Material: Aluminum alloy Product Feature: It is mainly solved in urban villages, basements, elevators, garages, villas, offices, warehouses and some other blind areas where signals cannot reach.
