I found a couple of wire loop and flat rectangular Saorview aerials I tried were pretty rubbish. Finally found that worked pretty well, but unfortunately can't find any links to it now. They had it in Curry's/PCworld, its a curved black rectangular thing, cost about €30. They had two types, a cheaper rectangular thing with an advertised range of 3-4 miles and this one advertised as 9 miles. Not on their site anymore, I'm afraid.
