It is likely that the TV aerial on your house points 29km east-southeast toward the transmitter at Waltham, if so you should be able receive Freeview but you may need a new (group W (or wideband) positioned horizontally) roof-top TV aerial.

It could also point 60km southwest toward the transmitter at Sutton Coldfield, if so you should be able receive Freeview but you may need a new (group E/W positioned horizontally) roof-top TV aerial.

Your aerial could also point 79km northeast toward the transmitter at Belmont, which you cannot receive Freeview from (but you can see analogue channels).

It could also point 8km northwest toward the transmitter at Nottingham, if so you should be able receive Freeview but you may need a new (group W (or wideband) positioned vertically) roof-top TV aerial.
