This makes sense, we have had intermittent issues with PRIME on the TV. 
The antenna is an external one, but isn't especially long (perhaps 
40-50cm). Based upon the antennas in the local area it appears to be 
pointing in the right derection.

As I said, we do have intermittent signal issues. Usually moving the 
antenna cable around a bit sorts it out! This suggests to me that it may 
be bad connection in the wall socket, which I will investigate tomorrow 
evening.
