TV Cables in Kenya
With the advent of satellite and digital TV broadcasting, more and more often the question arises of which cable for TV is better to choose - after all, the quality of the received signal depends on it. So, for example, when switching to satellite or digital broadcasting from analog TV, often the equipment does not tune to certain channels, the image may become fuzzy, blurry, sometimes ripples and interference appear on the TV screen, although a completely different quality is expected from modern technologies. The main reason for the occurrence of such defects is the technical inconsistency of the old line in relation to the new signal characteristics. It is logical that for the high-quality operation of television equipment, you will have to change the cable.
Speaking about the internal structure, we can say with precision that all models have a similar content.
As you can see, the principle of the structure of cables is the same, but the materials from which its structural parts are made differ from each other. How to choose a good option that would meet the technical char TV Cables in Kenya acteristics of modern television broadcasting?
The broadcast quality largely depends on the chosen cable. Today's market offers many options for a wide variety of applications. Before buying, it is worth considering some of the critical characteristics of the products.
Regardless of the manufacturer, any television cable for the adoption of a modern television broadcasting format must have a resistance of at least 75 Ohm.
Typically, either PE or PVC is used. In the first case, the shell will be white, and in the second, it will be black. Previously, it was believed that for outdoor installation, for example, when the antenna is on the roof or balcony of a house, a cable with a black protective sheath should be preferred. But today this indicator is not critical, and therefore some types of cables with a white protective sheath, for example SAT 703, can be used for both indoor and outdoor work. The main thing is to take into account the thickness of the protective layer. It is quite logical to believe that the larger it is, the better.
However, in this case, the entire structure becomes clumsy, respectively, the bending radius will be somewhat limited, this should be taken into account when planning the installation site (the presence of turns and corners).
It should consist of two filming layers. You should not purchase models with one layer, such a cable does not meet modern signal transmission standards. The materials from which the screening layers of the outer conductor are made are different. In the very first models of a television cable, the most common braided wire was used as an external screen. The main advantage of such a model is its low cost, but it is definitely not worth counting on receiving a high-quality signal, and even satellite TV. Modern models have a main screen made of metal foil and an additional braid, which is also made of metal alloys - it reduces the level of interference from radio equipment and household appliances.
As a rule, the central core is made of copper or other strong metal alloys. To provide strength, alloys can also be clad with copper. There are no confirmed facts that a copper core is of much higher quality than alloys of other metals, transmits a signal. But many experts recommend just such models of television cables.
The modern market provides for a large number of manufacturers, but this does not mean that everyone promises a quality product. It is worth paying attention to well-established manufacturers, for example Belden, Cavel, Commscope, Mediaflex. This rule also applies to the choice of antenna.
This parameter affects the range of signal transmission: the larger the cross section, the more confident the broadcast will be. For conventional antennas that are located no further than 30 meters from the receiver, classic options from 0.5 to 0.8 mm2 are suitable.
If the equipment is installed on the roof of a house, that is, at a considerable distance from the receiver, then the cable must have a conductor cross-section of at least 1 mm2. Otherwise, normal TV viewing will be disturbed by noise, snow and other artifacts.
Its ability to transmit a signal over long distances depends on the size of the cross-section of the cable.
This parameter is measured in decibels (dB) and indicates the amplitude loss per 100 meters of cable. The lower the indicator, the better the signal will be. Manufacturers are
