8. Application: 

   1) Outdoor Yagi Antenna with 10 Meters 75ohm Coaxial Cable (goes outside the building)

   2)  Indoor Signal GSM 3G Cell Phone Booster Dual Band Pico Repeater

   3) Indoor Ceiling Antenna with 5 Meters 75ohm Coaxial Cable (goes inside the building)

   4) Connetor  for Mounting

   

   Step1 Start by taking your phone up to the roof or other location outside to find where the signal is strongest.

   Step2  Temporarily mount the Outdoor (outside) antenna in that location. You may need to adjust and move the antenna later. More notes on Donor antennas here.

   Step3  Run coaxial cable into the building to a convenient loaction (attic, etc.) where you can also get standard power for the Signal Repeater.

   Step4  Place the Signal Repeater in that location and connect the coaxial cable to the Outdoor Side of the Signal Repeater and the Outdoor antenna.

   Step5  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.

   Step6  Connect coaxial cable between the Indoor antenna and the Signal Repeater output port.

   Step7   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.

   Step8  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.

Notes:

1. Had better make partition between two antennas, extend the distance. Forbid to turn-on equipment while the vision-distance of two transceiver antennas is within 10m, otherwise, the equipment will go wrong.

2. After connect the power, within 1 minute, the mobile phone with GSM signal can’t call near the equipment.

3. The end of Receiver Antenna should point outdoor, to the direction of receiving source.

4. Screw the joints while connected to antennas, avoids bad effect of signal coverage.

5. The adapter original engine equipped is AC100V~240V, take attention to the voltage range of input power.

6. This product is designed for indoor application, the temperature range is -5~45°C, at the same time, avoid dampness and drench.
