No signal from the antenna? Discover the causes and solve them once and for all!
The arrival of digital terrestrial television in Italy has brought many new features, new channels and new television formats, but also many problems: how many times do you happen to mysteriously disappear your favorite channel, and the word "absent or weak signal? Digital terrestrial improves the overall quality of TV channels, but needs a quality signal to work properly: below the reception threshold, the image simply disappears. What can be the cause of a weak signal? Let's see them together!
Black TV screen, what to do?
Have you already tuned in to digital terrestrial, but have the channels not yet appeared? It is usually the fault of the home system, such as the internal cables or the antenna itself, which may have rusted for years in the weather. Try to check this: ask your neighbour if he sees the channels you cannot tune to. If the answer is yes, you should call an antenna technician who will monitor the signals provided by the antenna with a field meter. In many cases, the lack of signal is due to incorrect antenna orientation, perhaps caused by wind. The technician should check the position of the repeaters and simply adjust the antenna accordingly.
A simple solution: Enhance the signal
Amplifying the TV signal is a simple and handy solution, ideal when only some channels of digital terrestrial are not displayed. All you have to do is buy a signal amplifier: it is a device that you can easily find in electronics stores or on the internet. In the instruction manual you will find all the information you need to install it at its best. If you've already tried this solution, you can always contact an experienced antenna specialist in your area to check your TV system! In fact, often, replacing the antenna is an almost obligatory route, especially if it is an old model, left in the weather for many years and perhaps not in compliance with European regulations.
Lightning: How to save the antenna!
The storm can be a fascinating spectacle, especially if you look at it safely behind your windows. Maybe while the thunderstorm rages outside, you are comfortably lying on the sofa listening to the thunder. But, at some point, a thought of crossing the brain as fast as a lightning: the TV antenna. It's out. On the roof. At the mercy of thunderstorms. This time he will not hold up. Sometimes it resists the weather, other times your TV antenna is struck by lightning. Very often it happens that the digital terrestrial loses signal during the storm.
How to do it? The most classic, banal and functional method is lightning protection. If you are already thinking about DIY solutions, don't do so. It is very dangerous to climb the roof to install a lightning rod of fortune built perhaps following instructions on the Internet. Entrust the installation of a real lightning rod to specialized companies that will not create any damage to the roof, allowing you to discharge the energy of lightning to the ground. This will save the antenna, TV and electrical system.
