The antenna, cables, and other accessories of the booster kits shall not be modified without the
approval of the ANNTLENT company, otherwise it shall be deemed invalid.
INSTALLATION INSTRUCTIONS
（1）Installation of Outdoor Antenna
The booster's main function is to improve weak RF signals of an area. A simple formula: Input power+ Gain=
Output power. The signal strength from the outdoor antenna directly affects the efficiency of the indoor coverage.
It is very important to choose the outdoor antenna location in order to get the best signals.
Testing the signal strength received from outdoor antenna mounted in site by mobile phone:
Please select the top of building to install the outdoor antenna if total floors are less than 7 floors, and shall
try your best to select places like balcony or platform lower than 7
buildings are over 7 floors, because the mobile signals are clean at less than 7
The mobile phone shall display full bar signals in location where the outdoor antenna is installed
The phone calls or data transmission shall be smooth and stable by 3 times testing in location where the
outdoor antenna is to be installed
As shown from the above illustration, testing the signals from A to E, and select a best place that displays
full bar signals to install the outdoor antenna.
Selecting the installation direction of outdoor antenna.
The outdoor antenna shall point to the direction of the tower, and it would be much better to keep line of
sight.
Please select the opposite directions for outdoor antenna and indoor antenna. If outdoor and indoor
antennas have to be installed in the same direction, please install them only after the signal quality is
tested and the self-oscillation is avoided. If the directional antenna is selected, the main directional angle
should point to the tower antenna.
If the performance is poor due to weak signals or poor phone call quality, please adjust the direction of
outdoor antenna or change its position in order to obtain the best calling effect.
The wide band booster supports all mobile operators or different mobile systems, so please adjust the
outdoor antenna direction to have balance between signals of different mobile operators or various mobile
systems.
