Detailed description of the adjustment of the cell phone signal amplifier
1. The indoor antenna should be installed far away from the outdoor antenna to prevent mutual influence. The indoor antenna and the outdoor antenna must be separated by a wall.
2. The indoor antenna should be installed at an angle of 2 meters above the interior wall of the house or installed upside down on the suspended ceiling.
3. Various connectors must be wrapped with tape to prevent water seepage from being oxidized, resulting in a smaller coverage of data signals in the house.
1. After installation, there is no actual effect at all.
First, check whether the indicator light on the amplifier server is on, so as to determine whether it can be connected to the power supply.
Then make sure whether the selection of spare parts such as amplifier server and wireless antenna is appropriate, and whether it can be paired with the type of mobile phone card used by itself.
Determine if the amplifier server's indoor and outdoor sockets, regulators, and wireless antennas are properly connected.
2. After installation, the data signal has been improved, but no calls can be made
Make sure the outdoor antenna is properly installed.
Make sure that the data signal at the location of the outdoor antenna is stable, and the orientation of the wireless antenna is as far as possible towards the data signal sending communication base station.
Make sure that the length of the data signal transmission line of the outdoor antenna and amplifier is moderate (preferably not more than 40 meters, not less than 10 meters).
How to never get it done, adjust a higher power amplifier or ask a professional operator to overhaul it.
3. The sound quality of the call is not very good
Adjust the azimuth of the outdoor antenna, so that the azimuth of the wireless antenna is as inclined as possible to the communication base station for data signal transmission.
Change the direction of the data signal transmission line from the outdoor antenna to the amplifier server (the approaching straight line, the route should not be turned too much, and it should not be turned at a right angle of 90°).
The route from the outdoor antenna to the amplifier server should use a coaxial cable above 50 ohm-7D as much as possible.
Determine whether the distance between the outdoor antenna and the indoor antenna can be too close (too close will cause self-excitation). It can be installed on the same level to avoid the data signal sent by the indoor antenna being received by the outdoor antenna to generate infinite loop expansion (self-excitation).
4. The data signal is improved after installation, but the coverage is not large
Make sure that the data signal of the part where the outdoor antenna is installed is sufficient and strong.
Make sure that the data signal transmission line from the indoor antenna to the amplifier server is not easy to be too long, the connector of the route is properly intact, the raw materials of the route meet the regulations, and the regulator is not connected too much.
Appropriately install indoor antennas according to specific conditions.
