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
