Installing a mobile signal booster is not an overly complex task, but it does require basic knowledge of radio engineering and skills in using a rotary hammer. For successful installation, you need to correctly select a model for your premises, calculate the necessary length of coaxial cable, and ultimately perform all work according to recommendations.
1. Determine Cable Length.
The first section of cable is needed to connect the receiving (outdoor) antenna and the GSM booster. The cable length should be determined so that the outdoor GSM antenna is installed outdoors in a location with the best signal reception and with maximum line-of-sight to the operator's base station.
2. Install the Outdoor Antenna.
When installing, it is important to consider that to achieve maximum signal isolation between the indoor and outdoor antennas, there must be a height difference of at least 5-7 meters. For example, if you are installing in an apartment on the 1st floor, the outdoor antenna is recommended to be placed at the level of the third floor or higher. However, its final installation location is determined at the discretion of the installer. If you do not know where the carrier's base station is located, you need to assemble the entire structure "on the fly": take the receiving antenna outside, connect the coaxial cable between it and the booster, connect the indoor antenna via the second cable section, and only then power on the booster.
Important!!!
It is forbidden to turn on the booster without both the outdoor and indoor antennas connected to prevent equipment damage.
To accurately determine the direction for installing the outdoor antenna, two people will be required: one will slowly rotate the receiving antenna, and the second, near the service antenna, will measure the signal level using a mobile phone. This way, the best direction and location for installing the receiving antenna can be determined.
3. Install the Indoor Antenna.
The indoor antenna is recommended to be placed in the room where a stable signal is most important, or in a way that the signal is evenly distributed throughout the premises.
4. Install the Booster.
It is necessary to choose an optimal location for the booster indoors so that the cable lengths to both the outdoor and indoor antennas are minimal. The operating temperature range for the device should be within +5...+40 °C, with humidity not exceeding 85%.
