Types of Aerial Installation in the London Region
If you are thinking of upgrading your current TV aerial ready for the 2012 digital switchover in April you may be pleased to know that there are many types of aerial installation in London to choose from. Here we take a look at some of the factors about aerials that will determine whether an aerial is suitable for using with the digital signal and Freeview.
Factors That Determine Suitability Of Your Aerial
Freeview provides residents with around 50 TV channels in total, along with radio stations. To be able to pick up all these channels will all depend on your aerial. Factors that are taken into account include the design style of the aerial, the “group” of the aerial and its location on your property.
A Standard Aerial
The standard aerial is typically known as the Yagi aerial. This is one of the most commonly seen types of aerial installation throughout London. This type of aerial is generally seen mounted on a pole and will consist of rod and reflector along with elements. The amount of elements on an aerial may differ substantially between aerials. These types of aerials are directional and generally the more elements, the better the signal. To pick up an analogue signal a standard type with around 10 to 18 elements in more than adequate. However these types are not commonly used in new aerial installation throughout London today as the aerials only get some of the frequencies that are transmitted and so may not pick up all the digital TV channels offered by Freeview.
Digital High Gain Aerials
High gain aerial installations in London are common when residents wish to watch Freeview through their aerial and live in an area where the signal strength is poor. These types of aerial have not one but two reflectors and some of the aerials have as many as 100 elements, however 45 and 75 elements are more commonly installed. Aerials such as these can ensure that residents are able to get all the Freeview channels available.
Other Types Of Aerials
There are other types of aerial used such as indoor and loft mounted aerial installations. London residents who want their aerial installed in the loft may find that reception suffers slightly due to electrical interference from the home along with problems from roof tiles and even plumbing can cause loss of signal strength. Aerial installers may use satellite grade cabling to connect your aerial and set top box so as to help compensate for signal strength loss.
Positioning Of The Aerial On The Roof
When it comes to roof aerial installation in the London area, positioning of the aerial is crucial. The best place for your aerial is as high off the ground as possible and many aerial fitters install aerials on poles to ensure the best possible signal strength. This is especially true in areas of London where the signal strength is medium to poor.
