DIGITAL RECEPTION WHAT'S
NEEDED
Digital Television
Aerial reception is slightly different from the Analogue
signals as each channel carries approx 8 Digital compressed
channels, which means that if one of these channels is weak through
your existing T.V. Aerial then a few channels will break up or
disappear altogether.
A good quality T.V.
Aerial will help and must be aligned using a Digital T.V. Aerial
meter to ensure that all Digital frequencies are being received
otherwise channels will be missing a good quality T.V. Aerial fitted
on Heavy duty brackets will cost £110.00 fully fitted with a 2 yr
warranty, more rooms can be added to this system and we offer a
complete four room upgrade for £230.00 fully fitted (includes all
new brackets and cabling) Go to our
Aerial page for more info on T.V.
Aerials.
These are the Signal Levels needed to have trouble free viewing for
Digital Television any more Signal or any less can cause Digital
Breakup.
