Digital Aerial Installation information for TV
'Digital Aerial' signals unlike analogue aerial signals, can receive far more channels in the same amount of space using digital technology. This means that digital tv aerials, or better worded, aerials compatible with digital, can receive far more channels via digital transmissions.
Digital aerials are a relatively new phenomena - There is actually no such thing in the UK for TV, as a digital aerial.
In order to receive digital aerial signals, it is necessary to have certain parameters in place to receive trouble free digital viewing. For reliable digital TV aerial reception, according to the CAI, it is important to have an aerial with a balun, to match the impedance correctly and to have the correct carrier-to-noise ratios, as well as the correct quality, benchmarked double screen cable to enable the best possible reception.
What does this mean to you?
Digital signals need to have certain things in place, to enable the aerial that is receiving digital to be able to work properly, receiving the digital signals and transferring them down a digital compatible aerial rig, to the digi box, or digital enabled tv (ie. freeview digital)
This is not to say that your analogue aerial will not work. It might do, but it is much less likely to be reliable.
Digital aerial signals either perform perfectly or very poorly, this means that if your TV aerial is not up to the job it will freeze occasionally at best, or at worst, not work at all. This phenomena, where the signal dips below a certain parameter, is called the digital cliff effect. Whereas with analogue pictures, they get ‘grainy’ or ghosty, digital pictures start to break up and freeze, known as pixelation.
The other thing to be borne in mind is that some transmitters do not transmit digital signals at all.This means that you have to try and receive your digital signals from another transmitter. At least for the time being that is.

This serves to highlight the importance of digital signal compatible aerials and professional installations, which is why
