How To Choose Outdoor Antenna For Cell Phone Boosters 

The working of a cell phone booster begins at the outdoor antenna end. It is one of the three major components of a cell phone booster. The outdoor antenna captures the cellular signals that are to be amplified by the device. 

After capturing the available cellular signals, the outer antenna transfers them to the signal booster’s amplifier unit. The function of signal boosting is performed at the amplifier end. After the signals are adequately amplified, they are sent to the indoor antenna that broadcasts the coverage area’s increased signals. 

Significance Of Antenna Gain 

Donor antennas have some gain associated with it that is measured in dBi. The value of antenna gain indicates the extent to which the signal is focused. An antenna does not amplify the signal. dBi is a logarithmic scale. Zero dBi gain suggests that the signal is not focused while 10dBi gain indicates that the signal received from a particular direction is ten times more than the signal received from other courses. Using a high gain outdoor antenna helps increase the indoor coverage area and the booster system’s downlink power. 

What Are The Two Types Of Outdoor Antennas?

Two types of outdoor antenna are:

Omni-Directional Antenna

Omni-directional antenna pulls in signals from all directions equally. Because they work 360 degrees, they need not be aimed. Hence their installation is quite simple. The omnidirectional antenna does not prove useful in all kinds of locations. It is suitable for areas that receive signals of multiple carriers coming from several cell towers. The antenna is ideal for boosting numerous carrier signals.

Unidirectional Antenna 

The unidirectional antenna works 45 degrees and is suitable for pulling in signals coming from a particular direction. They take more effort and time for its installation, as they have to be aimed perfectly towards the cell tower. In locations with just one cell tower operating, an omnidirectional antenna will not be able to pull in the strong signals. A unidirectional antenna is the correct choice in such situations. 

Inter-cell interference, which results from multiple cell towers broadcasting on the same frequencies, can be handled effectively using directional antennas. 

The cell phone booster’s output depends on the strength of the input signal supplied through the outdoor antenna. Hence, the efficacy of the outdoor antenna influences the overall performance of the cellular signal booster system.
