The problem with choosing a new TV aerial is that unless you have a good knowledge of how strong the TV signals are in your area, it’s difficult to know whether you need a high-powered TV aerial or not.
Local areas can have features that affect TV reception, such as hills or tall buildings. For example, in Bath TV aerial installation advice will depend on where in the city you are located. So it’s a classic case of using a firm that has strong local knowledge and can recommend the best type of aerial for your location.
Some people recommend what’s called a “wideband” TV aerial, which has differently spaced antennae. They’re called wideband because they can receive a wider range of signals than the ordinary aerials, which are called “grouped” aerials. A wideband aerial may be overkill for many households, who will get perfectly good reception with an ordinary aerial.
The BBC has a useful reception search tool – http://www.bbc.co.uk/receptionsearch.
Mobile Auctions Alter Frequencies
Your installer has to be aware of where 4G phone masts may have lately started transmitting, as these too can affect TV reception. And every time the next generation of mobile phones is launched, certain frequencies are auctioned off to carry the mobile phone signals. This often affects the TV reception in an area. So your installer has to be aware of future developments that may affect TV in your area. They also have to understand where the transmitters are, what type and strength of signal they are putting out, and what direction it is coming from.
A competent installer can also run a signal test if necessary to see where the strongest signal is. They’ll have detailed information and expert advice about the best aerial type, given the local transmitters.

The Closest Transmitter May Not Be the Best
Some transmitters, for example, don’t transmit all the Freeview channels – they have a cut-down version which only includes about half the channels available.
Your installer may advise tuning to a transmitter that is farther away or has a weaker signal but has the full range of Freeview programmes. The installer will then advise on how to get round the problem of a weaker signal, possibly through the use of a wideband aerial.
