Have not tested it lately Andy,but only 10 days ago on the southern rivers most places i got at least 60 channels on Freeview.
And i have an old caravan ariel on the roof.(altho a good one) It was a case of pointing it in the right direction with no trees in front.
I know most of the best reception areas down south for recieving signals and they are Cantley and Hardley mill,Bramerton woods end, Reedham and Surlingham ferry inn.
WRC,Beccles and Oulton broad, New inn moorings can be pretty patchy.
