2.1 lnstallation Location Requirement
The repeaters should be used to cover the indoor area.Humidity and temperature of working
environment can affect the reliability of repeater. so, temperature, humidity, dust, interferen-
ce, power, space requirements and other tactors should be considered during installation of
repeater.
（1）It is important that the repeater is installed in a place where is away from excessive
heat, direct sunlight, moisture and with proper ventilation. Do not place the repeater in
an air-tight enclosure.
（2）Installation height should be easy for RF cable wiring, heat dissipation, security and
maintenance.
（3）There should be an independent and stable power supply.
（4）Lightning protection is recommended for all in-building installations. Take extreme
care to ensure neither you nor the antenna come in contact with any electrical power
lines. stability.
2.2 lnstallation of Outdoor antenna
The repeater’s main function is 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 by mobile phone:
Select an outside antenna location on the roof of the building to install the outdoor
antenna, using a cell phone to find the strongest signal from the cell tower.
When installing the outdoor antenna on a building with 7 stories or greater, try to select
a place like a balcony or platform lower than the 7th floor because the mobile signals
are clearer at less than 7 stories.
The mobile phone should display full bar signals in location where the outdoor antenna
is to be 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.
