My mistake, I had to wiki but you are indeed right.
[QUOTE=trapdoor;787747]The antennae will work just fine, but reception is hampered by the way DVB-T works, and something called the 'digital cliff' where with analogue, you see a gradual degradation of the signal, eventually the picture/sound disappearing into the noise, whereas with DVB-T, you see no degradation until just before the noise floor, where you will see increasing picture and sound breakup, after a very small signal reduction, you will just see a blank screen and no audio.[quote]Agreed.

I upgraded in my X3, and it's nice to be able to get pretty much all of the DTT channels (except the encrypted pay channels, so don't expect to get Sky Sport 1/2  ) but any attempt to use on the move is frustrating. |
The problem with movement is that the system was never designed for moving receivers. There is no signal fading profile for a moving reciever and no provisions for time varying doppler shift like you find in a mobile phone for example. The reciever would be expected to break up as soon as it start moving, although the Hybrid TV tuner may have a data buffer to prevent the latter, I don't know because I don't own one.
