Looks great going into my Samsung smart tv via rf in the bedroom. Rf also used for hd signals for freeview hd so it can't be that bad?
RF is the basis for all terrestrial and satellite signals. It is how the information is encoded onto the RF signal which determines the quality. Good widescreen PAL analogue signals encoded RGB would have the edge on lower-rate digital SD transmission. However, and it is big however - your TM box (or an older SKY box for that matter) is taking a low-quality colour signal (composite - not RGB video) and mono sound and modulating it onto an RF carrier for distribution around your home. This is the point Rob is making. It's the lowest quality of video (and no stereo sound) - only a notch above VHS video.
