David, Alex: That is not true. The DVB-T2 standard is just that much more efficient than DVB-T (reflecting nearly 15 years more development). The mode selected for the BBC B multiplex is only very slightly less robust than the post-switchover mode for the other multiplexes, which is about the same as for Mux 2 and Mux A now. The difference in radiation pattern between two channels is typically larger than the difference in the margin required between a DVB-T and DVB-T2 multiplex.

Now that the commercial multiplexes are going to use 64QAM 3/4 mode, not 64QAM 2/3 as BBC A and D3&4 will, the HD multiplex should definitely be more robust than them.

maureen: I find it quite amazing that he managed to buy a analogue only TV unless from some second hand source, is he absolutely positive that it is purely an analogue set and that DVB isn't seen mentioned on the remote control?

However, any of these low priced Freeview boxes seen in places like Argos etc should be perfectly suffice for his needs provided the TV he purchased does have a scart socket?
if not then any Freeview box purchased has to be of the type with an RF modulator so that the signal can be fed into the TV's aerial socket.

Of course needless to say he will require a suitable aerial, although advice on this only being possible by having knowledge of his post code, this to enable checking of the signal level expected at his location.
