Notes on the installation and use of mobile phone signal amplifiers

Choose a model
The mobile phone signal amplifier mainly selects the model according to the signal coverage area and the structure of the building. The signal is too weak and the coverage is not complete; the signal is too strong and interferes with outdoor signals.
Arrange the antenna
Directional Yagi antennas are used outdoors, and the direction of the antennas can be pointed to the base station of the mobile company as much as possible to achieve the best reception effect. Omni-directional antennas can be used indoors, and the installation height is 2-3 meters. The number and location of the antennas installed are related to the indoor area. It is related to the indoor structure. In an indoor unobstructed range of less than 300 square meters, only one antenna needs to be installed, for a range of 300-500 square meters, two antennas are required, and for a range of 500-800 square meters, three antennas are required. In addition, the signal sent by the indoor antenna cannot be received by the outdoor antenna during installation, otherwise self-excitation will occur.
Installation of mobile phone signal amplifier
Generally, it is installed more than 2 meters above the ground, and the distance between the installation position of the equipment and the indoor and outdoor antennas should be the shortest distance (the longer the line, the greater the signal attenuation) to achieve the best use effect.
