How to choose a cellular amplifier: TOP 5 models in the rating

Cellular signal amplifiers operate on the principle of an antenna. They pick up signals from the base station and amplify them to maintain normal mobile and Internet connections. Today, several hundred different types of models are produced, so figuring out how to choose a cellular amplifier is not always easy. To do this, you need to study the technical characteristics, as well as consider specific devices from well-known brands - all this information can be found in the presented article.

Types of amplifiers

There are different types of repeater for strengthening a cellular signal. Common devices such as an antenna, cellular or Internet signal amplifier:

1. An Internet signal amplifier is a small antenna that is connected to a router or modem. It is used only to strengthen the Internet signal. This gadget does not work separately - it must be connected to a modem. The device is compact, does not take up much space and does its job well.
2. The amplifier antenna performs the same function, but it is not connected to the modem via a standard USB cable. Communication is carried out using a special high-frequency cable with connectors. Strengthens the Internet signal and Wi-Fi.
3. When considering how to choose a repeater, you can also pay attention to the classic cellular amplifier.Compared to other devices, models of this type have their own antenna. It is placed inside the house and forms a coverage area. Strengthens mobile signals as well as Internet connections.

Amplifier Design

To understand how to choose a cellular amplifier for a summer residence, it is useful to understand its structure. As a rule, the model is a passive antenna with a USB port for connecting to a modem. Moreover, the kit usually includes wires with which you can immediately connect to a 3G or 4G module.

There are also models that include a modem with several LAN ports and SIM card slots. Depending on the set of accessories, connection to a laptop or PC is carried out via a cable or modem, as shown in the diagram.

The rating of cellular amplifiers is presented by the best models, which consist of 3 main elements:

1. The actual amplifier (repeater).
2. External antenna.
3. Internal antenna.

Each element is connected in series to the other using a coaxial cable. The repeater itself works when connected to an outlet with a standard voltage of 220 V.

Top cellular amplifiers include models with 2 types sets:

1. Two-module ones consist of an external antenna and a repeater, which has its own (internal) antenna built into it. Since there are few elements, installation is noticeably simplified. But it is worth keeping in mind that such a device is not very powerful. Therefore, if you need to understand how to choose a cellular signal booster with higher performance, it is worth considering other models.
2. Three-module ones consist of a repeater and 2 separate antennas. They cost more, but give a stronger signal. In addition, antennas can be placed at a maximum distance to cover the entire network area.

How to choose an amplifier

To choose the right model, you need to understand how a cellular amplifier works, as well as what technical characteristics it has. Before purchasing equipment, it is recommended to pay attention to several parameters.

External antenna type

The operating principle of a cellular communication amplifier is similar to that of an antenna. The device receives a radio wave from a source and converts it into high-frequency vibrations. There are 2 types of external amplifier antenna:

1. Directional - it needs to be directed only in the direction of the base station, since it is in this case that the signal will really be amplified. Models with a directional antenna are used in cases where the station is located at a large distance.
2. Omnidirectional has a small signal “capture” radius, but it receives reflected waves better. This device is well suited for areas with dense urban development.

Antenna protection

When learning how to choose a GSM repeater, you need to pay attention to the protection of the external antenna. Usually a box made of plastic or metal is installed on it. The design looks more attractive and also receives protection from any external influence. Typically, such models use directional antennas.

There are also devices that do not have a box. As a rule, these are omnidirectional antennas. They are cheaper, but lose in terms of aesthetics. In addition, the lack of protection leads to rapid wear and corrosion. When analyzing how to choose a communication amplifier, this point should be taken into account.

Degree of protection

The best cellular repeaters last for several years without any complaints because they have reliable protection. You can determine it in the model description according to the IP standard. The minimum requirement is IP40, although it is better to consider equipment from IP55.You can check the compliance of the standard with the qualitative description of protection using the table.

Cables and connectors

If you understand which is the best cellular signal amplifier for a summer residence, you need to pay attention to the complete set. As a rule, the kit contains several connecting elements, including brackets and cables. Models must also be equipped with TS9 or CRC9 connectors. The kit also includes adapters for connectors.

When analyzing which cellular amplifier to choose for your dacha, it is best to choose a radio cable with a resistance of 50 Ohms and SMA-type connectors. The connection of such a device is carried out according to the specified diagram.

Communication standard

Having understood how a cellular signal booster works, it would be a good idea to pay attention to the communication standard it supports:

• 2G – allows you to receive only voice calls on phones;
• 3G – in addition to calls, provides Internet access, but only at low speed;
• 4G – provides both calls and the Internet, and at high speed.

Gain

The best cellular amplifier for a summer residence should have a fairly high gain. This indicator is measured in dB:

• for models that amplify the Internet signal, the optimal coefficient value is from 7 to 20 dB;
• for mobile signal amplifiers - from 25 to 50 dB.

There are also models with higher coefficients. They are installed in rural areas. Moreover, if the signal is weak both at home and on the street, it is better to take the maximum - from 75 to 85 dB. And if the signal outside is good, but weak at home, it’s worth considering devices with 60-70 dB.

Top 5 amplifiers

When considering which cell phone booster to choose, you need to study several models from well-known brands.If you study the reviews and technical characteristics, you can make the following rating:

1. S2100 KROKS RK2100-70 – amplifies 3G signals. Gain coefficient is from 60 to 75 dB, covers an area of ​​up to 200 m2. This device can be used both in a residential area and in a car. The gain level can be adjusted using a manual switch.
2. Titan-900/1800 PRO – repeater with 2 antennas (external and internal). Serves all communication standards from 2G to 4G. Designed for large premises up to 1000 m2. Equipped with indicators to help you position the device correctly. Has a certificate from the Ministry of Communications of the Russian Federation.
3. TR-900/1800-30dBm – this repeater supports all communication standards and covers an area of ​​up to 1000 m2. Operates in a wide temperature range – minimum -10, maximum +55 degrees. Receives signals from a station located at a distance of up to 20 km.
4. PROFIBOOST E900/1800 SX20 – the device is powered by a microcontroller, so all settings are performed automatically. Supports all communication standards and has IP40 protection. Designed for rooms up to 500 m2. Reliable model from a well-known brand.

Repeaters provide stable reception and amplification of the communication signal. When choosing one model or another, you need to take into account the characteristics of your area and the remoteness of the tower.So, for dense urban areas or villages, it is necessary to consider models with maximum gain.
