It is one thing to be able to buy a TV antenna , and another to know how to install it properly to ensure a stable signal. Indeed, in cases where the incoming TV signal is too weak, the tuner will not be able to decipher it, and the TV itself will not reproduce the image and sound. As a result, the user often has to think about how to amplify the antenna signal (TV antenna booster).
In this review, we will look at how to amplify a weak and unstable TV antenna signal together with you.
Prerequisites to follow to boost TV antenna
When installing antennas :
Consider the characteristics of the area
The television reception signal is guaranteed and depends on the terrain. If possible, install the antenna at the highest point adjacent to your home. This ensures the desired height of the antenna device. If necessary, use an additional mast, securely reinforcing it with metal strikers.
Choose the optimal design of receiving antennas
The requirements for this are: simplicity and reliability, sufficient spatial selectivity, the ability to skip a wide frequency band, a small input resistance and a high signal gain coefficient.
Check the antennas for installation accuracy and let it set up
To do this, select the optimal ratio between the size of the antenna elements of the required signal and the selected stations. Correctly warn the design in the room, anesthetize the antenna on the broadcasting center or repeater.
Use special amplifier antennas for signal enhancement
The dimensions, design, and connection method of such a device can vary greatly. When choosing an amplifier, pay attention to the frequency characteristics and noise level specified in the technical documentation. The configuration of the amplifier used for a specific model of TV receiver is a professional responsibility. Otherwise, the efficiency of the device will be low.

TV antenna booster: choosing a good location 
The quality of the television signal depends directly on the location of the antenna.
Concrete walls, metal fences, and structures are very disruptive to signal transmission. Therefore, it is generally recommended to install it outside the house, on the wall, so that it can work properly. Also, if you know where the nearest transmitter tower is, the antenna should be deployed in its direction for a stable signal.

Change the design to boost TV antenna
Almost any antenna can be a special TV signal amplifier . It operates from a 220 V network. For the right choice, it is important to know some parameters: the noise coefficient (it should be as low as possible, no more than 2 dB), the amplification coefficient (is calculated depending on the presence of branches and its length).
Usually, the antenna design is thoughtful, taking into account the standard search for ethereal. It can be changed using any conductive metal object: wire, cable , balcony dryer, central heating batteries, etc. Large-area aluminum and copper objects are best suited.
On the other hand, metal objects that do not come into contact with the antenna will interrupt the signal. Some antennas require special adjustments before use, so check whether the correct frequency range is set to accept either signal.

Advantages and disadvantages of connecting an amplifier to boost TV antenna
Connecting an amplifier to a TV antenna promises tangible benefits which are:
- a sharp increase in signal strength even when using the antenna of the previous design;
- no more worrying about where to place your TV.
Indeed, this is especially noticeable if an active antenna is used, in which the amplifier board is part of the design. In this case, the power of the signal transmitted to the TV is so great that even an entire bay of cable will not become a tangible obstacle. When using an external amplifier, it will have to be placed closer to the antenna.
On the other hand, if you intend to connect an amplifier at home, you should keep in mind the possible disadvantages and limitations:
The complexity and high cost of equipment are increasing
Even if you use the simplest amplifier unit that can be soldered, you will need new parts: fasteners, connectors, power supply, special tools, etc.
You have to take care of the needs
In fact, any amplifier transforms the incoming signal into its exact copy, which has a high power. The additional energy must come from somewhere. Therefore, you need an external adapter connected to the mains. A set-top box or a TV that has an active antenna socket with voltage transmission via the charger is suitable as a power source.
Not in all cases is the use of amplification appropriate
To create a powerful copy, you need a high-quality original, and if the TV signal is clogged with noise and interference, the amplifier will also amplify them. Therefore, even filters and tuners will not always be able to separate the useful signal from the unwanted ones.

TV antenna booster: what is the syphase effect?
If you take a pair of identical antennas and want to spread them horizontally and so that the phases of the signal are the same, it is possible to amplify it significantly. For example, if a single antenna gives a coefficient of 7 dB, then you double it to 10 dB, composed of four parts at 12 dB, etc.
Indeed, the main rules of the Syphase grid are: the pieces can be purchased or manufactured independently, but must be the same. It is important that the "floors" and "rows" are completely symmetrical, with the same length of lines, twisted sweaters. Frames made of insulating materials, such as wood or plastic, are used for fastening.
