TV signal amplifier and its varieties

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, a device that can provide the best level of receiver performance, can usually help. 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

A TV signal amplifier for cottages or cottages 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 by which the input signal is characterized. 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 receiver is located at a great distance from the telecentre, and also in order 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 question related to such a device as a television 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 fact is that the channels of reception 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 sum up the choice of the device, it should be noted that the television signal amplifier should have the largest possible gain at a weak frequency.

Amplifiers for cable networks and their types

Installation of amplifiers for cable TV subscribers can take place 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 kind is the simplest. Devices that apply to it, usually installed in apartments, where you need to connect multiple TVs. 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

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