The Different Types of TV Aerial
Every year thousands of TV owners around the UK find that they need a new TV aerial fitted. Since the digital switchover from analogue television, there has been a surge in the buying and fitting of TV aerials across the country. A new TV aerial will improve the picture quality you receive on your screen in most cases, especially if you haven’t had your aerial changed in a while.
TV aerials take on a number of different forms. Each type of aerial has its own specification, and whilst most are suitable for use in all locations, if you have particularly poor coverage in your area, only certain types of aerial will provide the kind of quality picture you are looking for.
Finding the right TV aerial requires a lot of prior research, and an expert understanding of the variables that can determine which type of TV aerial you need. A lack of expertise and knowledge about TV aerials is the main reason why a lot of people choose to have their TV aerial sourced and installed by a TV aerial company, as opposed to trying to buy a TV aerial and fitting it themselves. Which, if you choose the wrong one can be more costly than having one expertly fitted in the first place.
Yagi TV Aerial
Yagi aerials are the most commonly used form of TV aerial in the UK. They are fitted to a property on a mounted pole which is situated on the roof. A Yagi aerial has a large rod, with a reflector positioned close to the pole, with smaller rods sitting alongside the main rod that help to capture the signal. They can pick up the vast majority of digital TV stations in areas that have moderate-good signal coverage. However, they don’t work as well in areas where the network coverage is poor.
High Gain TV Aerial
High Gain TV Aerials are purpose built for use in poorly service areas where the signal coverage is minimal. Similar in build to Yagi Aerials, they have 2 large reflectors that are used to capture and boost the signal received by your antenna in order to give you the best picture possible. In certain circumstances, high gain aerials may be mounted on higher masts so that the signal is clearer and not obstructed in any way. High gain aerials are the choice of many homeowners who live in rural areas, where there may not be a transmitting station nearby.
Grid TV Aerial
Grid aerials themselves are not a stand-alone type of aerial and are only suited for areas that have very good coverage. A grid aerial itself is an add on for the Yagi aerial to further increase the signal quality it delivers. Whilst they are not designed to pick up all digital channels, they do help to strategically increase the quality of transmission being received. They are made up of a small number of components that are placed in front of the Yagi’s reflector to boost the signal.
Indoor TV Aerial
Your humble Indoor TV Aerial is not built to pick up digital transmissions. So it is almost impossible to receive digital channels using this type of aerial. Newer models of indoor aerial, can in some instances pick up a low quality digital signal, but only in the right environment and with good coverage. Indoor aerials are no longer the choice for many homeowners as they often experience interference from other electrical devices in the home, such as computers, mobile phones, tablets etc. To get the best performance out of an indoor aerial, it is advised that the aerial is placed high up in the building, on a windowsill pointing in the direction of the transmitter, and kept away from electrical appliances.
Loft Mounted TV Aerial
Designed for high coverage areas, Loft Mounted TV Aerials are suited to properties where the environment has a crippling effect on outdoor aerial, such as very strong wind and weather patterns that could damage the aerial itself. As they are positioned in the loft, a high signal coverage is needed as roof tiles, plumbing and cabling in your loft can all impact on the quality of signal that is received by the aerial. A signal booster would normally be fitted to help improve the signal quality further.
