Just want to share this good read:
Why is Digital Reception a problem? The only reason why digital reception should be a problem is because of the past. We have had analogue television for many years, and most people can get a reasonable standard of reception. However, the frequency bands allocated to television have already been "filled up" with the old four channel broadcasts of BBC 1, BBC 2, ITV and Channel 4. When channel 5 arrived, there was no more room, and so many transmitters had to use bands previously reserved for equipment like Video Recorders, and later DVD players. In order to have any more channels the only answer was to change to digital broadcasting. Digital television needs less transmitter power, and less frequency bandwidth, than does the old analogue TV. Just one of the old channel numbers can now contain half a dozen or more digital programmes.
