4G mobile phone signal amplifier

Equipped with the communication operator's dedicated line 50-5 5D FB 50 ohm RF coaxial cable feeder.

The three-band high-power mobile phone signal amplifier can solve the problem of vodcom,mtn,cell c, telkom 4G network signals. but not support 5G network,   One unit supports almost all operators, namely  vodcom,mtn,cell c, telkom. It is especially suitable for places with poor signals or no signals, such as mountains, caves, basements, power distribution rooms, equipment rooms, office buildings, remote rural areas and high-rise residential buildings, densely packed self-built houses, etc. After installation, it is equivalent to a base station, and the signal is immediately full, and you can make calls and surf the Internet, which is more than enough to cover about 300 square meters.

To select the appropriate feeder thickness, the following factors need to be considered:

1. Cable loss: Generally speaking, thick wires have less cable loss than thin wires.

2. Impedance matching: In order to match the impedance between the antenna and the cable, it is necessary to select the appropriate feeder thickness.

3. Practical application: In addition to theoretical factors, practical applications also require consideration of limiting factors, such as cost, available space, etc.

The selection of mobile phone signal line is based on the effect of feeder. Of course, the thicker the better. However, the thicker the better, the more expensive it is. The connectors are also expensive and more troublesome to handle.
