They then discover that the reason the old TV had "failed" was
actually because the aerial had blown down (alu mast corroded) So they
call out an aerial installer. He tells them not that the mast has
failed and the antenna is OK, but that they need a whole new aerial

digital set won't work otherwise. So he installs one. Presumably
because he's shifting old stock while he still can, this new aerial is
an _analogue_ antenna.
