It is irrelevant that the signal strength is high. The reflection are
the killer.

Indeed, as I stated in my first reply. I've also had excellent reception
from a loft aerial before. I'm not saying that it will work in every (or
even many) cases, but as it is a free bet, you might as well try it.

BTW it is an AERIAL.

I knew it didn't look quite right...
