Cell signal boosters mainly have three parts namely an external antenna, an amplifier, and an internal antenna. The external antenna is used to collect the outside signals and these signals are transferred to the amplifier for boosting their strength, and these boosted signals are then transferred to the internal antenna for rebroadcasting to the required areas.
External antennas are an important part of the cellular signal boosters, as the efficiency of the device depends on it. These antennas are responsible for collecting the outside signals for amplifying. There are different types of antennas used in a booster and you have to be aware of them for choosing the right one for you. Hence, we are listing some of the common types of antennas used in a cell signal booster.
Types Of Antennas
Omni-directional antenna and uni-directional antenna are the common antennas that are used in signal boosters. These antennas have their own specialties, hence you have to choose one that meets your requirements. Below, we list some of the important features of these antennas for your knowledge.
These are generally used where there is already a good signal strength. It can accept signals in a 360-degree pattern. However, this may not be the ideal choice for you if you are living in a rural or remote area, where there is a large distance between your home and cell tower. The range of these antennas is short, i.e. they cannot accept signals from longer distances. In addition to this, as these antennas accept all signals, it does not have any filter. So it can give you issues if there are a large number of nearby towers from different service providers.
Pros Of Omni-Directional Antenna
- Easy installation
- Will amplify all the signals in your area
- Ideal to boost 5G E, 4G LTE and 3G signals when building materials are the main reason for your poor cell reception.
Cons Of Omni-Directional Antenna
- Short range
- Gain is lower than uni-directional antennas
- Not suitable for rural areas
- Can create issues such as “signal noise” in extremely busy urban areas.
They are suitable for rural and remote areas, as they can pull signals from far distances. These antennas are designed to pull in signals in a 45-90 degree field in the direction to which they are pointed.
Pros Of Uni-Directional Antenna
- 3x more powerful than the omni-directional antennas
- Ideal for using in rural and urban areas
- Great for boosting signals when the distance from the cell tower is the main problem
Cons Of Uni-Directional Antenna
- It is best for boosting only one or two service provider’s at a time
- You need to be careful with the installation, as it should be pointed in the direction of the cell tower
- You might need some technical knowledge to find the direction of your cell tower
When selecting an antenna you need to consider different factors including your location, the number of carriers’ signal you want to boost, the signal strength in your area, etc. It will help you to select the right type of antenna for your cell signal booster.
