3 HOWTOINSTALLYOURNEWCELLULAR
BOOSTER(forVehicleinstallations)
3.1 Outsideantenna:
Adopt the car magnetic antenna or chuch antenna.
Function: receive the signal from the base station, through
the feeder to booster. Meanwhile transmit back the signal to
the base station after enlarge the signal.
3.2 Wirelessvehicleinstallations:
Generally, hidden inside the corner nearby the power
supply
Function: two-way, full-duplex amplifier the inside &outside
signal of the car, and the maximum uplink is to 2W.
![](/img.php?id=2462543&img=bg6.png)
3.3 Insideantenna:
Adopt the car magnetic antenna or chuch antenna.
Function: Transmit the enlarger signals to the mobile phone,
and receive the uplink car phone signal to booster.
3.4 Feeder
When install, hide it in the decoration materials or pads.
Function: Connect the feeder, antenna, and mobile phone
seat.
3.5 Powersupply
Adopt the9V-12V power supply, and it is extremely
convenient for direct feed by the car power, also we support
the car charger.
3.6 Installnote:
When install, try to separate the inside &outside antenna to the max
straight distance, and make the inside and outside antenna could
not mutual see (also don't mutual see each other through the roof
skylight)
