Since it was first created there has been no way that a television can work without having a television aerial or antenna. When the first television sets were installed in a home the owners were also quite surprised to find that they would need to have a long thin piece of metal on the roof or the side of the house to be able to watch any of the newly transmitter programs. A television aerial picks up electromagnetic signals from a broadcasting station and converts them into images on our screens. These aerials have undergone a period of evolution which is why they are able to receive digital signals today. They can still become damaged so you will still need the services of a TV aerial repair Stroud based company like https://steveunettaerials.co.uk/our-services/aerial-services/tv-aerial-repair/tv-aerial-repair-stroud.
The earliest antennas were simple things. They were large wire based aerials that had to be mounted on a rooftop to be able to get a clear signal from the broadcast station. These antennas had very limited range and depth and you would have had to have been very close to the broadcast signal to get a decent picture.
The 1950s saw the first leap in Aerial technology. Detection Direction was created so that signals could be picked up from specific broadcasting Towers. For the first time we could receive more than one channel for a different region. For example, a viewer in Gloucestershire could get local West based news or news for Wales
Digital and smart aerials have taken the ability to watch television to an even greater level.
