There is no alternative DVB-T antenna or amp available. The antenna is located in the rear heated screen. This will combine to a slightly reduced signal strength. DVB-T is not designed to work while moving.

Not right I'm afraid.
DVB-T (UK DTT) Runs within the current UHF band and the multiplex frequencies are interspersed between analogue channels in pre-DSO area's and in post-DSO areas are often on the same UHF channels as the old analogue channels. 405 line TV frequencies are known as Band III and were sold off to be used for PMR & Tetra
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.
The Hybrid tuners can be made to work 'TV in Motion' by coding (using navcoder) but unless you are practically on top of the Tx, it's worthless.
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.
