What Are The Components Of Cell Phone Boosters?

Quality of cellular communication is a crucial tool in times of emergencies, for maintaining personal relationships and handling business operations in real time. Unfortunately the signal strength cannot be high in every place you go. Signal strengths see wide disparities according to the features of the location like terrain, forest cover etc. Shifting between tower ranges of numerous transmitting towers while you are in a moving vehicle can also influence the strength of the signals that your cell phone receives. 

A signal booster is the simplest answer to all the queries about increasing cellular signal strength. The device increases the strength of the cellular signals available at your place and rebroadcasts them to your cell phone.

Components Of Cell Phone Boosters

The minimal number of components of cell phone booster contributes to the simple operation and maintenance procedures of the device. The components of cellular signal boosters are given below. 

Outside Antenna

For the signal boosting operation to start, the cellular signals available in the area have to be captured first, and the function is performed by an external antenna. It takes in the outside signal and sends it to the amplifier. The higher the point where the external antenna is placed the better the coverage will be. 

Two types of external antenna are:

Omni-Directional Antenna

It takes in signals coming from 360°coverage range. It is ideal for locations that receive signals of multiple carriers enabling the booster to amplify all the carrier signals.

Unidirectional Antenna

Unidirectional antenna captures signals within 45° range. Unlike urban areas, remote rural locations will usually have just one cell tower and the external antenna has to precisely capture the signals coming from the cell tower. The best choice in a rural area is a unidirectional antenna. 


The most important component of cellular signal booster is undeniably the amplifier that boosts the strength of the cellular signal sent in by the external antenna. The decibel gain of the amplifier indicates the extent to which the signal is boosted. It is generally recommended that amplifiers in home signal boosters should have decibel gains of +60dB and more. 

Inside Antenna

After the amplifier boosts the signal strength to required levels, it sends it to the inside antenna that performs the function of rebroadcasting boosted signals. Internal antennas for homes are of two types:

Dome Antenna

Dome antenna is mounted on the ceiling and it broadcasts boosted signals to every direction. The antenna is suitable when a single floor in a building has to be covered. 

Panel Antenna

Panel antennas are usually mounted on walls and broadcast cell reception to a single direction, making it the ideal choice when multiple floors of a building have to be covered. 

The selection of the best cell phone booster frees you from the trouble of disturbed cellular communication due to the dropping quality of cellular signals.
