Digital Aerials

Digital Aerial installations unlike analogue TV 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'. This is an often mis-quoted term used by some disreputable aerial companies to up sell you an un-needed new TV aerial!  However, Digital Aerials are what most people call aerials for digital!

In order to install an aerial to receive digital aerial signals, it is necessary to have certain parameters in place to receive trouble free digital viewing.  For reliable aerial reception it is important to have an aerial installation with a balun, to match the impedance correctly and to have the correct carrier-to-noise ratios, as well as the correct quality, the bench marked double screen cable is to be used to enable the best possible reception. And what does that mean you ask?

 

What do digital aerial signals mean to you?

Aerials for 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 aerial 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 but can be tested FREE of Charge for your peace of mind.

 

How Do 'Digital Aerials' Compatible With Digital Perform?

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 or pixelate occasionally at best, or at worst, not work at all.  This phenomena, where the aerial signal dips below a certain parameter, is called the digital cliff effect.  Whereas with analogue aerial 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.
