It is possible to get all the freeview transmissions if you have TV aerial installations done for you. However, you ability to receive these transmissions is determined by the suitability of your aerial according to its size, group and the location you are in, or how you place it.
There are two types of installations that can be done: there is the outdoor and the indoor one. The problem with indoor aerials is that they are in most cases not suitable for getting freeview reception. However, it can be used in locations that have strong signal strengths.
In addition, there are two types of TV aerial installations that you can choose from. These aerials come in different styles that you can use for your digital television and those that are used for analogue televisions. The Yagi aerial is a standard type that consists of a reflector rod that has 10 to 18 elements on it. This kind is usually mounted on a post or pole with the rod pointing to the direction in which the transmitter is. This installation is good for analogue televisions and it works well if the reception is perfect. Areas with poor digital receptions require digital high gain TV aerial installations. These have two reflectors and up to 100 elements on it. It does provide freeview reception in area that would have been impossible to get to.
The group to use in any aerial installation is determined by the reception in your area and your location. Most aerials use the normal group when receiving transmissions. However, when you cannot get freeview transmissions from the same transmitter it would force you to replace your aerial with a wideband one, which is also known as group W. This type of installation covers all types of groups. When selecting a service provider for TV aerial installation they will normally be able to inform you where the best place for your instrument will be. Depending on your position and where you live the aerial fitters may advise that you have your new aerial installed on a pole to make sure you get the best signal from it.
The best position to mount any outdoor TV aerial is on high grounds pointing to the direction of the main transmitter. Position it away from others so that it can get good transmission without being hindered in any way. Moreover, placing it on a higher ground prevent it from being blocked by tall buildings or hills.
