15dBm Dual Band GSM900 DCS1800 Cell Phone Signal Boosters , Variable Signal Amplifier
Signal Amplifier Description:
In mobile communication, it is inevitable that macro-cell coverage cannot cover weak or dead zones; to use repeater is a good choice in these areas. Dual Band GSM DCS variable band repeater is suitable for the local operator who need to select variable band.
15dBm Dual Band Variable Band Repeater allow small to medium size indoor areas have reliable radio communications for first responders. Automatic gain control allows stable output power even when the handheld is close to the repeater, which protects the donor site from interruption. The unit is housed by a compact and light alumina casting enclosure.
The built-in external LCD accessible from the bottom of the enclosure allow the uplink and downlink gains, Output Powers, Alarms and so on be configured and optimized easily on site without additional tool. Signal strength indicator helps find donor signal source and set up the system in the field without additional equipment.
Signal Amplifier Features:
1. Uplink/downlink frequency can be adjusted.
2. Built-in Saw filter provides high out of band rejection
3. Built-in switches and signal strength indicator allow find donor signal source and set up the system on site without additional equipment
4. External 100-240V AC universal power supply
5. Indoor wall mount
6. Heatsink convection cooling and low power consumption
7. Built-in ALC provides stable output power even when the handheld is close to the repeater to minimize the interference to the donor site
