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.
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, scanning the area and the discovery of
several directions of signal reception. Choose the direction with the best signal reception.
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 )
