Any other installation question or need more proffessional suggestions to deal with your mobile phone signal problems, please feel free to contact with us!!
What is the installation pictures or the installation steps:
- 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
