Are rooftop TV arials now all obsolete, what with digital TV, satellite TV,
etc? I don't watch TV myself, but I am renovating the exterior of my house
and wondered if I can remove the old TV Arials without any likelihood of
their being missed in the future. Or do people receive digital TV signals
via old arials? The arials in question were erected in the early 1990s, I
believe.

Not at all - digital terrestrial TV (Freeview) uses the same aerials as
analogue TV. As long as the aerials are in good condition, big enough,
and the correct group, they are still useful.
