ok i see what u mean.
i live in a 2 story house, i have down stairs, and up stairs is my parents, it is run as 2 house holds.
up stairs they have an aerial jack and get 1,2,3,c4,prime, etc
but downstairs we are running on rabbit ears and only get 1,2,3 but its very fuzzy and a real pain.
hope that make sense.
thanks for your reply
