mobile phone signal amplifer/booster/repeater  ST-1090B, make you keep in touch with others smoothly in everywhere.

mobile phone signal amplifer/booster/repeaterProducts instruction

Cell phone signal amplifier is designed to solve the blind signal designed for mobile phone products. As the mobile phone signal is transmitted by electromagnetic waves to establish a communications link, the building of the barrier, in some tall buildings inside the basement of some places such as malls, restaurants, places of entertainment such as karaoke OK sauna and massage, underground civil air defense projects, subway stations and many other places, cell phone signals can not reach and can not use the phone. Cell phone signal amplifier can solve these problems in a particular place as long as the installation of a mobile phone signal amplifier system, the entire range of mobile phone signals can be well used, to which staff or customers great convenience .

Installation Approaches

Fix up outdoor antenna reception on housetop

Technique Supporting

If still no signal receipt after activated repeater, please check if outdoor antenna point to signal tower or elsewhere have strong signal and check if strength achieve 

Please adjust the direction of outdoor antenna if it cannot call out

If strength is not steady, please check if outdoor and indoor antenna are too close. Please ensure the outdoor and indoor antenna have distance of 20 meters at least ,with a wall between and net a same horizontal line

NOTE

The distance between the outdoor antenna and the amplifier is not more than 30 meters

The outdoor Antenna not close to a large antenna, high-voltage lines, transformers, or metal mesh, etc.

The distance between the indoor antenna and the amplifier is not more than 40 meters

The indoor antennas do not close to the wall as far as possible in order to increase the coverage area

The indoor antenna and the outdoor antenna are advised to stay away from each other for more than one floor distance to prevent cyclic signal amplification

If lack of communication quality, please change the installation position of the outdoor antenna and adjustment the indicate direction of antenna

It is best to enclose waterproof tape at the junction, and prevent moisture narrow the indoor signal coverage area

Try to straight the cable, do not bend more than 90 degree
