  Product Description                                     telecom mobile signal booster gsm signal booster 3g mobile phone booster                                        SAMPLE ROOM                                          WHY CHOOSE LINTRATEK?                                  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 they can find themselves “out of coverage” ,no signal at all... Usually those places are either too far from the cell phone base station or located inside underground constructions, for example:   · Parking lots, tunnels · Big stores, office buildings · Cars, boats etc. · House in remote areas Lintratek come, to save you from the bad signal!!!          ·   Excellent Quality          ·    Exquisite appearance       ·    High Technology              ·    Considerate service                      FAQ and Sollution                 

F:After installed booster signal 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 booster. 5. Change another high gain receiving antenna.

F: Cellphone signal full bar, but communication quality bad.

Too closer distance of indoor and outdoor antenna,  need more separation far distance away between antennas.

F: After installed 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.

F: Works good for long time, suddenly signal bad.

1. Check outdoor cable connectors whether flooding water. 2. Check power lights whether working normal. 3. If cable not flooding water and power light working normal  then the booster could be problem need send back factory repair.

      Signal Booster Full Sets                                      · 1 - Outdoor antenna like YAGI antenna or panel antenna · 2 - Indoor Omni ceiling antenna  · 3 – Power adapter  · 5 - User manual · 6 - Mobile phone booster · 7 - 10 meters outdoor cable and 2 meter indoor cable   Product Show                                                        Signal Repeater Installation (Take KW20L-GD repeater as an example)    Step 1:  Install outdoor receiving antenna on roof or other good signal places, where cell phone signal must more than 4 bars of service. The outdoor receiving antenna generally adopts the yagi  or Logperiodic antenna, the antenna must be installed level, pointing in the direction the base station.     Step 2:  The outdoor receiving antenna connected to the indoor amplifier input port(BTS) through more than 10 meters jumper wire.     Step 3:  The indoor antenna connected to the amplifier output port(MS), the indoor antenna usually have ceiling mount or whip antenna, the antenna height to 2 meters more than the best.       Step 4:  After two antenna was connected, in the indoor and outdoor antenna under the premise of not look straight and separated by a wall, plugged in electricity.     Step 5:  Check your cell phone signal whether enhance , if it is not ideal, you can adjust the direction of the outdoor antenna or higher the installation position to improve. Note that goof outdoor signal is half of success.     Step 6:   The joint of outdoor antenna and feeder line should wrapped well with the waterproof tape, do the “Drop of bending” before the feeder line into the room, prevent the water through the feeder line into the indoor when rainy day.     Packaging & Shipping        Trade process:                                                                     Company Information

And connectors connect well.   3. If strength is not steady, please check if outdoor and indoor antenna is too close; please ensure outdoor antenna has distance of 10 meters at least, with a barrier and not in a same horizontal line.   4. Packed the outdoor connector by waterproof glue, otherwise wet reduce the signal cover area.
