As practice shows, the picture on the TV screen does not always satisfy the consumer with its quality. In such cases, a television signal amplifier can usually help - a device that allows you to provide the best level of receiver functionality. It does not lose its relevance even during the rapid development of cable technology. The fact is that such a device can be used by users of both collective networks and โcableโ subscribers.
Application out of town
The amplifier of a television signal for giving or a cottage is an excellent solution for people living outside cities. The fact is that in the absence of the ability to connect to a cable network, poor reception of an antenna signal, or simply the presence of several receivers (TVs), this device is indispensable. This is especially true in places where the level of natural noise negatively affects the quality of the signal. It should be noted that in such cases, experts recommend the use of such devices, taking into account a slight distortion of the levels that characterize the input signal. Before applying signals to the television amplifier, the level is equalized on each channel separately.
Antenna amplifiers
In the case when the signal receiver is located at a large distance from the telecentre, and also in order to compensate for the losses that occur on long cables, it is advisable to use antenna amplifiers. They are also often called "active antennas." When applied, improving the quality of the signal can be general (broadband) or separate (UHF and MV).
Amplifier selection
A very common consumer question related to such a device as a television signal amplifier: โHow to choose the right device for yourself?โ Here, some key parameters must be taken into account. The first of these is the operating frequency range. The fact is that the reception channels of the antenna itself and the amplifier must match. The next aspect is the maximum output level (if the device is good, then this indicator is not less than 100 dB / ฮผV). The third caveat is that the gain should be as close as possible to an indicator of 40 dB. Typical current consumption typically ranges from 10 to 60 mA. Summarizing the choice of device, it should be noted that the television signal amplifier should have the highest possible gain at a low frequency.
Amplifiers for cable networks and their types
Installation of amplifiers for cable TV subscribers can occur in various parts of the network. In this regard, there are a large number of models of such devices. Their choice primarily depends on the place where the device will be installed. The main types of such devices are house and main amplifiers. The first view is the simplest. Devices that relate to it are usually installed in apartments where it is necessary to connect several televisions. Main amplifiers, based on their name, are installed in cable lines. In most cases, they are placed in a sealed cast housing, so they can be located on any part of the network.
Satellite amplifiers
Satellite television signal amplifier is a relatively new device. It provides the user with the ability to receive both television and satellite signals. When used at a remote distance from the antenna, signal loss is compensated and distributed between several receivers. Such amplifiers can be built-in or work separately.
