I can't give you the specifics as it's only something I was watching in the background but as I understand it, there is no such thing as a digital aerial.

If your analogue reception is good already across all channels and in different weather conditions, then I believe there is no need to replace it at all....

It was a Watchdog program a few weeks back so may still be on iPlayer...

Hope this helps...
