20dBm EGSM 900MHz Variable Repeater / Phone Signal Enhancer Indoor Wall Mount
With Digital LED display
Signal Enhancer Description:
EGSM 900MHz Variable Bandwidth Repeater enable to amplify only the targeted operator’s signals and reject all the others effectively, it is, therefore, an optimal solution for the people who want to select the certain signal among different operators.
20dBm Single 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 down link 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 Enhancer 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 100-240VAC 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
