Raymond Healy: Judging by Google Street View photos taken May 2012 you have a single aerial pointing to Limavady.

This page is for the Londonderry (Sheriff Mountain) transmitter, which is also probably receivable at your location. You could potentially be tuned to Sheriff Mountain for BBC and UTV/C4/C5 rather than Limavady, perhaps because its signals are found before those of Limavady. Sheriff Mountain doesn't broadcast COM channels which carry ITV3, Pick, Dave, 4Music and others, so there's no chance of these being wrongly tuned.

You should go to BBC One and observe the tuned UHF channel number or frequency. Sheriff Mountain broadcasts on C44 (658MHz) and Limavady is on C50 (706MHz). Do the same for UTV: Sheriff Mountain is on C41 (634MHz) and Limavady is C59 (778MHz).
