Television technology has come a long way, and the way TV signals are transmitted and received also has changed. Analogue TV aerials were once the standard; however, they have now been replaced by digital aerials, as the UK completed its digital switchover in 2012. If you are considering a new TV aerial installation in Cheltenham, it is helpful to understand the differences between analogue and digital aerials.
How analogue TV aerials work
Analogue TV aerials were designed to pick up signals broadcast over the airwaves in a continuous wave format. These signals were highly sensitive to interference, which could result in poor picture quality. Factors such as the weather, distance from the transmitter, and physical obstructions often caused static or image distortion.
As analogue signals carry the image and sound together, any disruption affects both. This technology was simple but lacked the reliability and clarity modern viewers expect.
The benefits of digital TV aerials
Digital TV aerials are designed to receive digital signals, which are transmitted as data packets. This allows for higher picture and sound quality, even in areas with weaker signals. Instead of a snowy or fuzzy screen when the signal is weak, digital TV either works perfectly or not at all, eliminating partially degraded images.
Digital signals also support additional features, including high-definition programming and access to multiple channels through Freeview. These benefits make digital aerials the preferred choice for modern households. The BBC has more information on the type of TV aerial you need.
