4. Installation instructions for a fixed RF repeater

Important !
Before commissioning the system is recommended to contact the telecom service operator, which you want to
receive and amplify the signal to be informed about installation and operation of the device.

Installing the outdoor antenna

On the top of the building, choose a position liberated from the building, where your phone receives at least 2 bars
Choose so that is easy to install, assembled and maintained.
? Keep external antenna away from power lines, nets and solid metal construction, high voltage cables,
transformers as they can disrupt the antenna parameters.
? You can be killed if the antenna is near power lines/cables
Adjust the direction of the external antenna is required and exttremely important. Use the measuring device you
have,connecting it to the antenna. Select the direction of the strongest signal, adjusting the angle of elevation and
azimuth.
Ensure that the distance between the indoor antenna and the external antenna is not greater than 10m ( total length
of cable). To avoid sel-oscillation, the external antenna should be at 5-6meters above the indoor antenna, on a
vertical axis and in opposite direction ( as in the figure below )
For a proper installation, site selection is very important for the entire project. Using signal measurement devices,
like a spectrum analyzer, or a mobile phone application will help pointing the external antenna to the BTS and
obtain the maximum signal gain. Checking the operation of a cell phone is one of the easiest ways. Testing the
signal with the mobile phone is not as accurate compared to a spectrum analyzer,because it is much slower.
Best results are obtained if measurements are made with an external antenna connected directly to the phone, using
Net Monitor function, specified above.
The installation can be started after connecting the external antenna on the phone,
