1. How it works
Huaptec vehicle C35W-ED dual system provides a reliable two-way cellular coverage by
improving signal strength in any kind of vehicles where cellular reception is weak or
unreliable.
The system amplifies the signal from the nearest cellular tower and retransmits it at a
higher power level to the vehicle area. This manual provides simple installation
instructions that will make your cellular booster kit set in record time.

2. How to install
The kit parts should be installed at one and the same time before being connected to each
other.There are 4 steps: outdoor antenna, booster, indoor antenna, and power supply.
Afterwards, you will need toconnect the outsider/inside antenna and the power adapter to
the booster.
Outside antenna:
Mount magnetic antenna. Its recommended location is about 20cm/8inch from
the rear of the car. If you have a larger vehicle,try installing it at the rear roof.
The function of outside antenna is to receive the signal from the base station and
transmit it through the feeder to booster. Being bi-directional it also transmits the
signal back to the base station from the booster.
Vehicle booster:
The vehicle booster should be hidden in the corner of the car, near the power
supply.
The booster is a full-duplex amplifier and it improves the signal both inside and

outside the vehicle.
Inside antenna:
Small Patch Antenna which has 2dBi gain is adopted. The proposed location is
at 3/4 height of the glass which is shown in the installation graph. If your vehicle
is larger, it’s recommended to install it in the place where signal is weak.
The function of the inside antenna is to transmit amplified signals to mobile
phone and also back to the booster.
Power supply
Plug the system into 12V power supply, the vehicle charger can also work; the
booster can be fed directly by the vehicle’s power.
