Being a device that offers the best solution for cellular signal troubles and comes at affordable rates, cell phone booster is really a boon for people who are fed up handling cellular signal issues. The device is generally a signal repeater that captures the available cellular signals at a location and amplifies it to send it to the next point, in this context, the cell phones that require boosted signals.

The device has simple operation processes and minimal number of components, with external antenna, amplifier and internal antenna being its major components. In this session, we are discussing all the important details of the major cell phone booster components.

External Antenna   

It is at the external antenna end that the signal boosting processes begin. The external antenna is placed at outdoor points; let it be the outside of homes, top of vehicles etc to capture the cellular signals available at the outside. The outside antenna just functions as a signal capturing and transmitting device, and doesn’t alter the signal in any ways.

After the outside antenna captures the signals, it sends in them to the amplifier kept in indoor locations. Connections between external antenna and amplifier are established via physical cables. There is no single antenna type that suits all locations with differing geographical features and signal quality.

Outside Antenna For Homes And Buildings

Depending on the signal quality available at a location, two types of external antennas can be installed at homes and buildings.

  • Omni-Directional Antenna

As the name suggests, omni-directional antenna operates in 360  range and captures signals coming from all directions. The antenna type suits urban locations that have multiple cellular service providers operating around. It captures multiple carrier signals and performs the multiple carrier boosting operations perfectly.

  • Unidirectional Antenna

Unidirectional antenna operates within limited angles, with 45  degree being the common angle within which it operates. The antenna is especially designed for remote locations that receive signals from a single cell tower. The quality of the cellular communication especially at remote locations solely depends on how well the signals from the transmitting tower are collected.

Unidirectional antenna is installed by pointing towards the tower location to collect the signals sent out by it.

External Antennas For Moving Vehicles

Mobility influences the choice of electronic devices, and signal booster is no exception, which is why separate antennas are available for moving vehicles.

Two types of external antennas for moving vehicles are:

  • Magnet-Mount Antennas

The standard car antennas have lengths ranging from 4 to 12 inches and are usually mounted on top of vehicles with the strong magnetic base of the antennas. The antenna lengths are small in order to avoid the antenna length compromising the aesthetic appeal of the car.

  • Recreational Vehicle(Rv)/Truck Antennas

Stronger and durable external antennas would be required in trucks and recreational vehicles, as they will mostly be driven in harsh conditions. The design of the antennas ensures that they are strong and last long. The 2 to 3 feet long antennas usually have fixed installations that are drilled onto the vehicle tops.

Trucker antennas are usually spring mounted or mirror-mounted to absorbs the shocks caused by the rough driving conditions like hilly terrain, potholes etc.


The most crucial signal boosting function is performed by the amplifier. Upon receiving the signals captured and sent in by the external antenna, the amplifier operates on the signals to amplify them. The strength of cellular signals is expressed in decibels with the signal range spreading between -50dB and -120dB. As you near -120dB, the signals strength sees a continuous drop.

The decibel gain of the amplifier indicates its amplifying power. Higher the decibel gain better is the boosting power of the amplifier.

Inside antenna

The inside antenna performs the function of rebroadcasting amplified cellular signals to reception points that are usually located indoors. Depending on the area that has to be covered by the cell phone booster, one or more inside antennas can be installed inside buildings, homes and vehicles.

Inside antenna types differ according to whether the booster operates in a mobile or immobile area.

Inside Antenna For Homes And Buildings

Two types of inside antennas for homes and buildings are:

  • Dome Antenna

Dome antenna broadcasts amplified signals along all possible directions. Thus the antenna is suitable when a wide area has to be covered. Take for example a single floor in a building. A dome inside antenna efficiently covers the area.

  • Panel Antenna

Panel antenna broadcasts signals along a particular direction and not along all directions. The antenna is the perfect choice when multiple floors along a vertical line have to be covered.

The failsafe working of all the components of a signal booster is quintessential for the efficient functioning of the cellular signal booster.
