How to choose an antenna?

The antenna should correspond as much as possibleconditions and broadcasting standards in your area. Buying an antenna, we assume that we will operate it for more than a decade. And how can it be insulting when, after installing and tuning the antenna, it turns out that the reception quality of the signal is low or the antenna does not receive the necessary signals! Therefore, before making your choice and paying for the purchase, you need to learn how to choose an antenna so that in the future when watching TV shows do not experience disappointment. We will try to help you in the correct choice of antenna.

TV antennas: how to choose

In many houses there are collective antennas. If you appreciate the quality of the signals it receives, you will be able to determine which antenna you will need. For example, if this antenna does not catch only UHF channels, then you can buy only a DMV antenna for individual use. Well, if the collective antenna does not catch the meter channels (NTV, Russia 1, Channel One, etc.) or the quality of the received signal is unsatisfactory, then you should choose the all-wave antenna, which catches both meter and decimeter signals.

The features of radio signal propagation are such,that sometimes even the most powerful TV antenna can not provide the quality of signal reception, it gives out noise. These shortcomings can in some cases be eliminated by installing additional equipment (equalizer, filter, amplifiers). But, unfortunately, there are situations when it is not possible to achieve a noticeable improvement in the quality of the received radio signal.

Therefore, if you are planning to purchase a televisionantennas, it is advisable to consult a specialist who can measure the radio signal level. Knowing this indicator, a specialist can advise you a specific antenna model, which will most fully meet the conditions for receiving a radio signal in your home.

How to choose a satellite dish

Every year more and more people are buyingsatellite dishes. When you look at all these "plates", it seems that they are similar to each other and practically have no differences. But actually it is not. How to choose the right satellite dish and what should I look for? Hopefully the information below will help you with this:

1. Most often, a dish of a satellite dish is made ofaluminum, because this metal is very light and not subject to corrosive processes. But the aluminum antenna can easily deform. Therefore, when buying, be sure to carefully inspect the surface of the antenna and in the presence of its curvature or other defects, refuse to purchase.
2. A dish of a satellite dish can beis made of plastic with a thin metal coating. These antennas have a short service life, and in winter they easily adhere to snow, which degrades the reception quality of the radio signal.
3. The diameter of the satellite dish should be at least 90 centimeters. The larger the diameter, the better the reception quality of the radio signal.

How to choose a car antenna

Before you buy a car antenna,determine what type of type you need. There are external passive and internal active antennas. Internal antennas are located inside the car interior. They are small in size, and their installation is usually not difficult. To install an internal antenna requires the presence of a special amplifier, which is supplied with power.

External antennas are distinguished by highsensitivity. But they are subject to various environmental influences, as they are located outside the car. Therefore, the reliability of external car antennas is low.
