and send to the indoor antenna hereafter. If the distance between outdoor antenna

and indoor antenna is less than the required distance, the amplified signal

will go

back from indoor antenna to outdoor antenna. So it will lead to self-oscillation and

reduce the coverage area, also the bad calling quality could happen at the same time,

and the worse is that the mobile network could be influenced badly and the operators

will finally come to shut off the booster system.

If isolation can’t be achieved by the limited distance, the roof of the building or any

other barriers can be used in between to increase isolation.

Fix the donor antenna after selecting the best position, and adjust slightly its height

or angles in order to get the signals with suitable input power level and calling

quality.

Installation of Indoor Antenna

Proper antennas shall be selected according to the site conditions and the

requirement.

Omni antenna (Indoor ceiling omni antenna or whip antenna), is suitable to be

installed in the center and radiate all directions.

It is better to use a directional panel antenna when the coverage shape is long and

narrow (corridors, long row of houses in two sides, tunnels or elevators or rural open

space).

Connect the indoor antenna to the booster connector marked INDOOR with 5 meters
