TV signal amplifier and its varieties

As practice shows, the picture on the screenTV does not always satisfy the consumer with its quality. In such cases, a television signal amplifier can usually help, a device that allows for the best level of functioning of the receiver. It does not lose its relevance even during the rapid development of cable technologies. The fact is that such a device can be used by users of both collective networks and "cable" subscribers.

Application outside the city

The amplifier of a television signal for a summer residence orThe cottage is an excellent solution for people living outside of cities. The fact is that in the absence of the ability to connect to the cable network, poor reception of the antenna signal, or simply the presence of several receivers (TVs), this device is irreplaceable. Especially it concerns those places where the level of natural noise negatively affects the signal quality. It should be noted that in such cases, experts recommend the use of such devices, taking into account the slight distortion of the levels that characterize the input signal. Before the signal is sent to the television amplifier, the level is equalized on each channel separately.

Antenna amplifiers

In the event that the signal receiverlocated at a great distance from the telecentre, as well as to compensate for losses that occur on long cables, it is advisable to use antenna amplifiers. They are often called "active antennas". When applied, the signal quality improvement can be general (broadband) or separate (DMV and MV).

Amplifier selection

A very frequent consumer issue related tosuch as a TV signal amplifier: "How to choose the right device for yourself?" Here you need to consider some key parameters. The first is the operating frequency range. The point is that the receiving channels of the antenna itself and the amplifier must coincide. The next aspect is the maximum output level (if the device is good, then this figure is at least 100 dB / μV). The third nuance is that the gain should be as close as possible to a value of 40 dB. Typical current consumption typically ranges from 10 to 60 mA. To summarize the choice of the device, it should be noted that the television signal amplifier should have as much gain as possible at a weak frequency.

Amplifiers for cable networks and their types

Installation of amplifiers for cable subscriberstelevision can occur in different parts of the network. In this regard, there is 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 home and main amplifiers. The first view is the simplest. Devices that apply to it are usually installed in apartments where several TV sets need to be connected. Trunk amplifiers, based on their name, are installed in the cable mains. In most cases, they are placed in a sealed molded case, so they can be located on any part of the network.

Satellite Amplifiers

Satellite TV signal amplifieris 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, the signal loss and its distribution between several receivers are compensated. Such amplifiers can be built-in or operate separately.
