Nowadays, cell phones are ubiquitous because we use them for many of our daily activities, and because of this it is important to have good cellular connectivity. Cellular signals are radio waves that are meant for long-distance communication. Also, they are affected by factors like geographical features, buildings, weather conditions, construction materials, etc. One of the best ways to ensure good cellular connectivity is to use a cell signal booster. As the name implies, it receives a weak cellular signal, amplifies it, and retransmits it to your cellular phone. Shared below are the different accessories used in a signal booster.

A cellular signal booster consists of three units the outside antenna, the amplifier, and the inside antenna. The outside antenna is the input unit, and the inside antenna is the output unit.

Outside Antennas

Omni-Directional Antenna: This type of outside antenna receives signals from a 360-degree field and is primarily used for boosting signals from multiple carriers. However, its disadvantage is that it has less forward gain, and because of this, it is not suitable for capturing signals from distant cellular towers.

Unidirectional Antenna: This type of antenna receives signals from one direction, i.e. its field of capture is 45 to 90 degrees. It can capture signals from distant cellular towers because of its higher forward gain and are hence suitable for rural areas.

Indoor Antennas

Dome Antenna: This type of antenna is usually installed on the ceiling and retransmits boosted cellular signals in a 360degree field. Because of this, it is useful for covering wide open spaces, like halls. However, it can cover only a single floor because of the lower gain.

Panel Antenna: This type of antenna is suitable for retransmitting signals in a single direction, and can cover multiple floors because of its higher gain.


The length and size of coaxial cables used have a significant impact on the performance of a cellular signal booster. The longer the cable, the greater the loss in signal strength and vice versa. Listed below are the typical cables used in the installation of signal boosters.

RG-6: This is the most common type of coaxial cable used in residential wiring with an impedance of 75 ohms.

RG-11: This is a better version of RG-6 coaxial cable, and it is thicker with lesser loss in signal strength.

The other type of coaxial cable used is the one with 50 ohms impedance, and because of the lower resistance, the loss in signal strength is minimal. Using this type of cable gives the best performance in a cellular signal booster. However, the disadvantage of this type of cable is that it is thicker, compared to a 75 ohms cable.

The other accessories used in the installation of a cell signal booster are splitters, combiner/diplexer, taps, surge protectors, signal attenuator and filter, and pole mounts.

We hope that the article gave you a better understanding of the accessories used in the installation of a cell signal booster.
