Sorry, he is wrong - It's a communal satellite dish that replaced the communal standard ariel.
It was put up for Digital TV.
If I want freesat or sky they have to re-align it for the appropriate satellite. I know this for a fact because I had to get the sat. changed when I had a freesat box. I prefer freeview, so changed back.
It's definitely a DISH. 
Um, its a communal dish, which needed to be realigned/changed depending on whether one required freeview or freesat?
So, if you had it realigned when you changed from freesat to freeview, what did the other occupants do? presumably they all changed from freesta/sky to freeview, whether they wanted to or not?
I'm not being pedantic (heck, the orginal question was simply "is Dave still on freeview"), simply interested in how this works!
