Jackie Miles:

According to the Digital UK Coverage Checker, you are just 18 km from the KLnockmore transmitter, see Coverage Checker - Detailed View The channels used are: 31, 37, 29, 33, 36, 48. It is likely that you need to be using a wideband type aerial aimed at the transmitter on a bearing of 138 degrees.

When you say a " normal arial (sic)" ( you actually mean a normal aerial) do you mean one mounted externally on a roof or chimney stack or an indoor type? The indoor types will not be much good in your location so you need an external one properly mounted and aimed.

Jackie Miles: When you say a normal aerial, do you mean an indoor aerial or a rooftop/loft aerial. You're predicted to get a strong signal from Knockmore (18km away) so a decent rooftop (or possibly loft) aerial should be fine.
