This meant that the aerial on your roof was a vital component of receiving television messages sent out via relay towers. This was a relatively effective system. The main centre acting as a hub, All across the country people would percent aerials to receive the analogue waves signals. This signal would then be passed by wire directly into the back off the TV. The TV then converted the signal via a cathode ray onto the TV screen.
Aerials are still and essential part of the process even though we have now switched over to digital. The work of this TV Aerials Swansea based company is still very relevant. The main problem with the analogue system is that it relied on waves. Waves of information are susceptible to being disrupted. It doesn’t take a lot to disrupt the wave. For example, por weather or atmospherics were blamed. Mountains were another. The remoteness of the area you lived in meant that watching TV was not always an option.
However digital changed that. It offers a more direct transfer of information based on binary code of zeros and ones. This is much easier for a tv to translate and it does not put off environmental features. This digital signal still needs an aerial to decode it. This is the 2 squared windowed shaped features at the back of the aerial. Digital allows high definition and crystal clear image whereas analogue can appear fuzzy. It’s why we used to have the Test card.« Back
