Why we should buy tri band signal booster ?
Cell phone becomes especially helpful when people get into critical situations. In case of emergency a timely call can save somebody’s life.
Unfortunately, there are still some places where one can find themselves “out of coverage”.
Usually those places are either too far from the cell phone base station or located inside underground constructions, for example:
How is the tri band signal booster works?
•The outside antenna catches the low signal from the mobile base station and delivers it to the cell phone
amplifier through the connection cable (coax).
•After the signal is accepted by the phone amplifier, the device amplifies it.
•Then this amplified signal goes through the connection cable (coax) to the inside antenna.
•And after that, the amplified signal transmits to the cell phone.
Where to use tri band signal booster :
Installation for tri band signal booster :
Step 1 Start by taking your phone up to the roof or other location outside to find where the signal is strongest.
Step 2 Temporarily mount the Outdoor (outside) antenna in that location. You may need to adjust and move the antenna later.
Step 3 Run coaxial cable into the building to a convenient loaction (attic, etc.) where you can also get standard power for the Signal Repeater.
Step 4 Place the Signal Repeater in that location and connect the coaxial cable to the Outdoor Side of the Signal Repeater and the Outdoor antenna.
Step 5 Mount your Indoor (inside) antenna in a productive location. You may need to adjust or move the antenna later. More notes on Indoor antennas and patterns here.
Step 6 Connect coaxial cable between the Indoor antenna and the Signal Repeater output port.
Step 7 Power up the system and check for signal inside the building. If needed, tune system by moving and or pointing the Outdoor and Indoor antennas until they get the most signal possible.
Step 8 Secure all antennas and cables, securely mount the Signal repeater and clean up the installation.
Of course there are still a few more things to consider but in general, this is the basic procedure. For more information, please contact us.
FAQ | Solutions |
After installed mobile signal booster not be very good,indoor signal coverage very small | 1.Adjust outdoor antenna's location and direction. 2.Check whether cable connected well. 3.Put more higher receiving antenna's position, which can received more good signal. 4.Change another bigger power mobile signal booster. 5.Change another high gain receiving antennna. |
Cellphone signal full bar, but communication quality bad. | Too closer distance of indoor and outdoor antenna, need more separation far distance away between antennas. |
After installed mobile signal booster not only signal be good,but also more bad. | Too closer distance of indoor and outdoor antenna, need more separation far distance away between antennas. |
Mobile signal booster works good for long time,suddenly signal bad. | 1.Check outdoor cable connectors whether flooding water. 2.Check power lights on mobile signal booster whether working normal. 3.If cable not flooding water and power lights working normal then the mobile signal booster could be problem need send back factory repair. |
